Bouncing Ball A 650-gram rubber ball is dropped from an initial height of 250 m, and on each bounce it returns to 75% of its previous height
(a) What is the initial mechanical energy of the ball, just after it is released from its initial height?
(b) How much mechanical energy does the ball lose during its first bounce? What happens to this energy?
(c) How much mechanical energy is lost during the second bounce?
