A student throws a ball upward in vertical direction with a velocity of 10 m/s. The mass of the ball is 20 grams.

a) Find the kinetic energy and mechanical energy of the ball at launch point.

b) If the maximum height of ball is 4 meters, how much of its mechanical energy is dissipated when it's in its maximum height.
