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

Explanation

We know that ivory ball is more elastic then wat clay ball. Therefore, the ivory ball will tend to regain its original shape in a very short time after the collision. Due to it, there will be large energy and momentum transfer to the ivory ball incomparison to the wet caly ball. As a result of it, the ivory ball will rise higher after the collision.
