Question

Two identical solid balls, one of ivory and the other of wet-clay, are dropped from the same height on the floor. Which one will rise to a greater height after striking the floor and why?,

MARKS App · Accepted Answer

As both balls are dropped from same height, before striking the floor their velocities will be same. Since the ivory ball is more elastic than wet-clay ball, therefore, ivory ball tries to regain its original shape quickly. Hence, more energy and momentum is transferred to the ivory ball in comparison to the wet clay ball and so, ivory ball will rise more than clay ball after striking the floor.
