A free-fall object eventually stops on reaching the ground. What happens to its kinetic energy ?

Prove that the kinetic energy of a freely falling object on reaching the ground is nothing but the transformation of its initial potential energy

Answer the following questions: Prove that the kinetic energy of a freely falling object on reaching the ground is nothing but the transformation of its initial potential energy.

A ball of mass 20 g falls from a height of 10 m and after striking the ground.It rebounds from the ground to a height of 8 m . (a) Calculate: (i)The kinetic energy of the ball just before striking the ground ,and (ii)The loss in kinetic energy of the ball on striking the ground,and (ii)the loss in kinetic energy of the ball on striking the ground. (b)What happens to the loss in kinetic energy in part(ii) ? Take g=10 m s^(-2) Neglect air friction .

A ball is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy when it reaches the maximum height ?
