Two identical solid balls, one of ivory ...

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?

Text Solution

Verified by Experts

Ivory ball is more elastic than wet-clay ball, therefore, it tends to regain its original shape quickly after colliding the floor and hence ivory ball wall rise higher.
