00:00So, this is rolling.
00:04This body is rolling here.
00:07See, we have kept this tape on hand.
00:11So, what is this body?
00:12It is rolling.
00:13So, we are taking translation motion of the body.
00:17This is translation motion.
00:19And this is rotation motion.
00:22In this way, this is pure rotation.
00:24When we rotate a fixed axis body, it is pure rotation.
00:30Now, in pure rotation, the velocity at the bottom is backward.
00:35See, the velocity of this point will be backward.
00:39And in pure translation, it is forward.
00:42Now, both are equal and opposite.
00:44So, the velocity at the bottom point will be cancelled.
00:48So, what will be the value of Vp?
00:50Zero.
00:51The velocity at the P point will be zero.
