03:16if you have the same size of the base, you can see.
03:18And第二個, the speed.
03:20As I said, I show you a camera on the 31st century,
03:24you can show the vehicle for
03:27the vehicle and the vehicle with the vehicle.
03:30You can notice the vehicle with the vehicle and the vehicle.
03:34And you can see the vehicle that is used as the vehicle.
03:37The vehicle is added to the vehicle.
03:42You can notice the vehicle with the vehicle.
03:45has fastened by the
04:08A
04:21A
04:24What is FK?
04:26The kinetic friction force
04:28FK is the power of the movement
04:32MuK is the power of the movement
04:34FN
04:36The power of the movement
04:38I have a table with 32
04:40That is the relationship between
04:44the power of the movement
04:46and the movement
04:48What do we see?
04:50I have a 10-10
04:52for the recovery done
04:54The했는데
04:55The éxitud
05:00of the power of the movement
05:02the power of the movement
05:04rough
05:22it is 5%
05:24so in fact that we can look at the
05:35angle of the gg
05:37and we can see that the gg is 1.3 kg
05:39and we can see the gg
05:41the gg is 1.5 kg
05:43so the gg is 3.3 kg
05:45therefore the gg is 2.5 kg
05:47and we can see that
05:49this gg is 1.5 kg
05:51How will the FK?
05:54How do you find the FK?
05:57FK is mu K is FN
05:59I want the FK
06:02say FK is about two and half
06:04so two and half
06:06mu K is FN
06:08How do you find FN?
06:11Galatina is Fy
06:14Fy
06:16The FG will be able to align
06:21sigma f y y0
06:23sigma f y y0
06:25sigma f y1- W
06:27then it's a change on the other side
06:29so f n0-w
06:31is that the same way
06:33the same way
06:3530? No!
06:3730-10
06:39so 30-10
06:41then we'll go and use fn 300
06:43to this
06:452.5 x u k
06:47300
06:49300 and 300
06:51I'm not going to add 2.5 to 2.5
06:53so I'm going to add 300
06:55300 here
06:57and 300 here
06:59I'm going to add 2.5 to 300
07:01How does it add 83?
07:03What is it?
07:05It's not a single one
07:07because it's an example
07:09This is an example
07:1133
07:1340 kg
07:15on the ground
07:17If you were to understand the power of the lumière
07:19the power of the lumière
07:21without no
07:44I'm going to end the power of the lumière
07:46do
07:51do
07:55do
07:59do
08:07do
08:13I want the Fs max, not the Fk, the Fk is actually moving.
08:18But it's on the same way.
08:21So I want the Fs max equals MuS by Fn.
08:25MuS by A, and A.
08:28How much was it? 15%
08:3315%
08:35So Fs max equals MuS by Fn.
08:39This is 15%.
08:41I want the Fs max equals Fn-W.
08:47The Fs max equals Fn-W.
08:49The Fs max equals Fn-W.
08:51How much is it?
08:53How much is it? 40.
08:55So it's 400.
08:57So Fn equals Fn-W.
08:59Okay?
09:00I'll return to the question.
09:01400.
09:02How much is it?
09:05How much is it? 15%.
09:07So Fs max equals 15.
09:0915% by 400.
09:11The final answer is 60 N.
09:13So the power that's used to be 60 N.
09:15So the power that's used to be 60 N.
09:17What's the second one?
09:19The power that's used to be 60 N.
09:21The power that's used to be 60 N.
09:23So the power that's used to be 60 N.
09:25How much is the power ?
09:27MuKa آ
09:41I want you to be 100 N.
09:43, I want to make the power of the Avian.
09:45So there is the Fn
09:47. This is the law. This is the law. It is good at the left
09:49, so this is 40 .
09:51So 40 is 40. 40 is 400.
09:54So 400 is aware of Fn here.
09:57And MuK has 11
09:59. So Fk is 11
10:01. So 40 N.
10:04What are you noticing? If you are noticing here
10:07that Fk is 40 N.
10:10But Fs Max
10:12max is 60 newton
10:15if the FK is more than the
10:18the second one
10:21what is the third one?
10:24the third one is if the power of 20 newton
10:27we go to the second one
10:30what is it?
10:33sigma Fx is equal to 20
10:36sigma Fx is equal to m
10:39a
10:40this is m by a
10:43sigma Fx is equal to 20
10:46m is equal to 40
10:49and the A is equal to 40
10:52so 20 by 40 is equal to 50
10:55this is equal to 2
10:58if you write sigma Fx is equal to the second one
11:02the important one is that
11:05the second one is equal to 20
11:08sigma Fx is equal to m
11:10a
11:11this is sigma Fx is equal to 20
11:14equal to m
11:15a
11:16this is equal to 20
11:17so you can do this
11:19I have another question
11:20I have a question
11:21if the power of 30
11:22you can do this
11:23if the power of 50 kg
11:24on the Fx is equal to the
11:25square of 37
11:27now the other one is equal to the
11:28the other one is equal to the
11:29the other one is equal to the
11:307
11:31but the other one is equal to the
11:327
11:33now I have a focus to the power of 37
11:34look at this
11:35if the power of the power of 200 newton
11:36They will be able to select 200 newton
11:38Notice the price of the cloth 1.3
11:40When the Shack is 1000
11:42You can choose the one to give it to the j
11:44you can pay the $10 and will give it to the price of the COS
11:46It'll be good for the student's counterpart
11:48Now, the end of the Shack is adding the power of the Shack
11:54It's not a way to push the effort
11:56How did I turn the power of the week?
11:58And I can't create the power of the AI
12:02If you really want to change the Fk
12:04If you can use mu k sub fn, it won't be able to use, because it will have a lot of information.
12:09But here, I need to explain.
12:12I'm going to show you the power of the sheds.
12:14What is the law?
12:15Not Sigma fx is equal to m sub a.
12:18Sigma fx is equal to the power of fx.
12:21It's not about the power of the sheds,
12:24which is negative power of the sheds.
12:27It's equal to m sub a.
12:29how do you say ftx is equal to m sub a?
12:32But if you use b by m, you'll kasin.
12:34If you use K dividing the ground, you'll use cosine,
12:37you'll use cosine,
12:38you'll use sine,
12:40you'll use sine,
12:42now the situation goes differently.
12:44using cosine,
12:46you'll use cosine.
12:48If you use Fk,
12:50this is 50,
12:52if you use 1.3,
12:54I will use cosine 37.
12:56I damage two,
12:58minus Fk,
13:0050 x 1.3
13:02When we hit it, we had 65
13:04Now, what can I do with this? I want to go to here
13:06So, I want to get 95
13:08But, I don't know if it's the same
13:10If we hit FK, it equals 95
13:13The same with the same
13:14So, 95 Newton
13:16This is the final answer
13:18That is the power of the vehicle
13:20The second question is to tell you
13:22I want to make the vehicle vehicle
13:24I have the FK
13:26Now, how can I get it?
13:28How can I get it?
13:30And, the FN is not
13:34How can I get it?
13:36Sigma FY
13:38Sigma FY
13:40Exactly. What do you mean?
13:42A normal force
13:44To be
13:47Ao
13:49It is spinning
13:51Why no?
13:52To be
13:53Features
13:56To serve
13:58So I have three powers for sigma f y, which is Fn plus Fty,
14:04which is the power to the normal force,
14:08minus W, which is 0.
14:11Now, W is going to go to the left.
14:12So what is going to happen?
14:13It's going to be 0.
14:15And Fty is going to go to the left.
14:18So Fn is going to W minus Fty.
14:21W is going to be 50 x 10.
14:26What is Fty?
14:29It's going to be 200 x 2, but it's going to be the sine of the 37.
14:34So I'm going to go to 50 x 10 x 200 x 6.
14:38This is 200 x 6, which is 120.
14:40I'm going to go to 500 x 120 x 380.
14:45So I'm going to go to this question.
14:47I want this 380 x 380 x 380 x 380 x 380.
14:51The Fk is going to be 95.
14:55So I'm going to go to the right.
14:57So I'm going to go to the right.
14:59So I'm going to go to the right.
15:0125%
15:02What is it?
15:03It's not a one of them.
15:03It's about an action.
15:06OK.
15:06I'm going to go to 9 x 36.
15:09This is a little bit of a piece.
15:11I'm going to go to the right.
15:11That's a little bit closer.
15:13I'm going to go to the right.
15:15Like I'm going to go to the right.
15:18Oh, I'm going to go to the right.
15:20There's an action in the right.
15:21I'm going to be a good person.
15:22There's a good person to recognize there's 25 degrees.
15:26If the
15:29thalgy was less, how would I consider it if the
15:34thalgy was less? Very easy. You can't forget the question in this question, but it's just about
15:40a level of level. The level of level is the level of level. The level of level is the level of level.
15:47It's a level of level. This is the level of level. I have this level of level of level.
15:52ومنحضر أملس
15:53كيف بدأ أوجد التسارع من القانون

18:01هلا بدنا نتذكر
18:03شغلة
18:04اللي F N ما طلعناها
18:06بدنا نطلعها
18:07فشو هي المركبة العمودية
18:09كيف بادر أطلع المركبة العمودية
18:11مركبة العمودية
18:12هي عبارة عن Sigma F Y
18:14منها من Sigma F Y
18:16بادر أطلع المركبة العمودية
18:17دائما مركبة العمودية
18:18شو بقابلها
18:19بقابلها الوزن إلى الأسفل
18:21أو المركبة العمودية للوزن
18:22وبالتالي Sigma F Y بتساوي إيه
18:24بتساوي F N
18:26هاي
18:27F N ناقص W Y
18:29المركبة العمودية للوزن
18:31هلا مركبة عمودية
18:32Is it equal to sine or cosine?
18:34Of course, cosine.
18:36The cosine is equal to sine.
18:38The cosine is equal to sine.
18:40Let's continue.
18:42The F is equal to W and Y.
18:44We're going to show you the right way.
18:46If F is equal to W, cosine 25,
18:48not sine.
18:50It's equal to sine.
18:52If it's equal to sine,
18:54it's equal to sine.
18:56But here is the sine.
18:58The F is equal to W, cosine 25.
19:00W is equal to sine.
19:02How did he get it?
19:0450.
19:0550 x 10 x 25.
19:0725 x 45.
19:09We're going to show you the number of 455.
19:11How did 455 look?
19:13We're going to show you the number of the previous one.
19:15The F is equal to W.
19:17The F is equal to 50 A.
19:19The F is equal to 1.
19:21Now we're going to show you F455.
19:24We're going to show you the number of two.
19:26We're going to show you the number of 210 x 4.
19:29Or 45.5 x 50 A.
19:31We're going to show you the number of Guys.
19:32We're going to show you how to make a be equal to 565
19:42yen.
19:44So, we're going to show you how to make a figure,
19:4737, that's the test.
19:50It has the pressure of the shadow of a speed
19:51of 200 Newton.
19:52Do you see how the speed of a speed is more than a speed?
19:54It's very easy, not like the speed of a speed.
19:56The speed of a speed, the speed of a speed, the cosine, and you can see it.
20:01So in the pocket, 50, which is 50.
20:03They are at 50.
20:04They are at 50.
20:05They are at 50, I don't know why.
20:06They are at 50.
20:07They are at 50.
20:08They are at 50 as they are.
20:09If you only have a speed of 1, it's 3 by 10,
20:11and you can't see you.
20:13and you can't see him as a speed of a speed.
20:14In terms of speed, this is how much of a speed is.
20:15There are going to be a speed of speed.
20:17How do I start to read it?
20:19In the moment, the power of fk is equal to mu k.
20:23I want the fk.
20:25This is the question.
20:27Mu k is equal to 3 by 10.
20:29How do I find the power of fk?
20:31Sigma f y.
20:33Sigma f y.
20:35What does it mean?
20:37Fn is equal to w.
20:39Right?
20:41It doesn't exist.
20:43It doesn't have sine or cosine here.
20:45It doesn't exist.
20:47So I have fn is equal to w.
20:49This is w.
20:51It doesn't exist.
20:53How do I say it?
20:5550.
20:57Fn is equal to 500.
20:59How do I start to read the power of fk?
21:01Fk is equal to mu k.
21:03Mu k is equal to 3 by 10.
21:05The power of fk is equal to 500.
21:07How do I find the power of fk?
21:09150 newton.
21:11Of course, the power of x is equal to x.
21:13andra one is equal to 0.
21:15What's wrongly ?
21:17I don't know.
21:18The power of X верх has equal to the part суп.
21:20Sigma f twice a metal ring.
21:22Another question is equal to the power of r externally.
21:23The power f of x equals to zero.
21:27Which is the Ft mutts as equal to the power of fk.
21:29The Ft has equal to 100.
21:31The power of M is equal to 150.
21:33So, the power of x equals to 50 newton.
21:35It is 50 N to the X
21:38Third, we need to get rid of the box
21:41How do I find it?
21:42Sigma F F X equals M A
21:47If I find this one, I find A
21:52Sigma F X is not 200-150
21:56It equals M A
21:58200-150 equals 50 A
22:01If 50 equals 50 A
22:0450-50 equals 1 M to each other
22:08This is the third
22:09I have a 38
22:11If you are aware of the difference between the x-axis and the x-axis
22:14and the x-axis and the x-axis
22:16and the x-axis
22:18is better than the x-axis
22:20and the x-axis
22:22which is for a day of night
22:24This is the x-axis
22:26and the x-axis
22:28and the x-axis
22:30What is the best to use?
22:32I can use the NAAA from the MOTAT
22:36Why?
22:37Because the temperature and the NAAA from MOTAT is much greater than the NAAA from MOTAT
22:45So the NAAA from MOTAT is the best
22:51Another third
22:51I think
22:53There is a left turn on the NAAA
22:54By the way, the NAAA from the MOTAT
22:56It is a way to manufacture the NAAA with a low-income
22:59What is the aim of this?
23:01at the edge of the car,
23:04when you increase the electric car JU 그리고 the electric car,
23:09you increase the collision between the electric car and the car.
23:12And then, we can cross the car in a second and not turn the car
23:16from this car.
23:18It is possible with this control car leg is a stop for every driver
23:22because it is zeroIn the collision between the electric car and the car
23:27so won't turn the car off to this car.
23:30There is an effective way for the technique, which is in the 39th.
23:37It is the effective way for the technique to be able to help the technique and the work and theыв
23:45or the spark and the action.
23:49But with the technique, it is important that it is important that it is to make some of the tricks
23:52that we use in our life, like a one-to-one, or another.
23:57Now, if you want to use this model, you can use this model in the 9th model, such as we talked about the Bilya, or the Bilya, or the Bilya, or the Bilya.
24:11These are the tools that you can use this model.
24:14This model is 26.
24:15This model is in the 39th model.
24:17I'll tell you that when you use this model, you can use this model.
24:22This model is easy to use.
24:31But when you use this model, it becomes easy to use.
24:35And when you use this model, it becomes easy to use the model.
24:44When you use this model, you can use it to ease the model.
24:49It's changing the model.
24:51As part of the model, it will be efficient on the model.
24:53It will need to be installed by the Bilya.
24:56Of course, you have to boost the model.
24:59The model is not just simply from the models.
25:03But it is also also right away from the model.
25:05I'll tell you that this muscle is very important.
25:09The muscle after a while, the muscle is very important.
25:14It's going to happen to these muscles.
25:17Like the muscle that's present in the recourse.
25:19It's going to cause the muscle.
25:22It's going to cause a problem.
25:23It's going to cause a problem to the muscle.
25:25It's going to be a change in the muscle.
25:27This is all that changes.
25:29It's going to be a muscle.
25:30Like this.
25:31This is like this, the only thing is like a way to make a collision reaction.
25:36And that will make a collision reaction related to the collision reaction.
25:42It's like the collision reaction is going to make a collision reaction.
25:46If it's a collision, it'll turn into the collision reaction between the collision reaction».
25:55That's what would be followed by that.
25:57So the person who is a difficult person
26:02is to have a hard time
26:04and if he is moving he is feeling a good
26:06What is the treatment?
26:08It is that he is putting a
26:09a
26:11a
26:12a
26:13a
26:14a
26:15a
26:16a
26:17a
26:18a
26:20a
26:21a
26:22a
26:23a
26:24a
26:25I don't have one question yet.
26:26What's this question?
26:27In the paragraph 17, I'll tell you about the eukalyptown power to the eukalyptown power.
26:323 so 8.
26:33Neukalyptown power to make and write and write as a video, Porque it's written in the description.
26:376.
26:38Mesh.
26:39Even the eukalyptown power to make an eukalyptown power.
26:437.
26:448.
26:458.
26:469.

27:2018.
27:2121.
27:2222.
27:23How does it look like this? Why? Because it's a very high level.
27:28So, this is a very high level.
27:31We also want to cut this like this.
27:34How does it look like this?
27:36This is also a very high level.
27:40Also, we have to look at this.
27:43This is a very high level.
27:45This is a very high level.
27:48We have a question from 41 and 2.
27:52.
28:07.
28:11Formationally,
28:14We appreciate the fire protection.
28:20We appreciate the fire protection.
28:30We appreciate the fire protection.
28:38Okay, the second question is, is this person's fault on the vehicle or on the vehicle or on the vehicle or on the vehicle?
28:44Yes, of course.
28:46Because of this, it is the vehicle.
28:48Because when it comes to the vehicle, it doesn't work.
28:50So, because the vehicle's fault is to enable the vehicle and on the vehicle.
28:53So, it depends on the vehicle's fault and on the vehicle.
28:57Then, we have to add the vehicle's fault on the vehicle and on the vehicle's fault.
29:03So, let's look at this.
29:05This vehicle's fault is to keep in mind this vehicle.
29:12So here I have a part of the
29:38Then there is a power of the movement between his head and his head
29:42And the third one is a power of the movement between his head and his head
29:47This is the lesson
29:48And alhamdulillah and al-salamu alaykum wa rahmatullahi wa barakatuh
29:52In the name of Allah
