Solution: You drop a ball from a height of 2.1 m, and it bounces back to a height of 1.3 m.(a) What fraction of its initial energy is lost during the bounce?(b) What is the balls speed just before the bounce?(c) Where did the energy go?(d) What is the balls speed just after the bounce?

Problem

You drop a ball from a height of 2.1 m, and it bounces back to a height of 1.3 m.
(a) What fraction of its initial energy is lost during the bounce?
(b) What is the balls speed just before the bounce?
(c) Where did the energy go?
(d) What is the balls speed just after the bounce?
