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

Answer:

                The ball which is more elastic rises to a greater height after striking the floor. Ivory is more elastic than wet-clay. Hence the ball of ivory will rise to a greater height. In fact, the ball of wet-clay will not rise at all, it will get flattened.
