Two identical solid balls, one of ivory and the other of wet clay are dropped from the same height on the floor. After striking the floor,
A
Ivory ball will rise to a greater height than wet clay ball.
B
Ivory ball will rise to a lesser height than wet clay ball.
C
Both balls will rise to the same height.
D
Data is insufficient.
Answer
Ivory ball will rise to a greater height than wet clay ball.
Explanation
Solution
: As the ivory ball is more elastic than wet clay ball, therefore it will tend to regain its shape instantaneously after the collision. Hence, there will be a large energy and momentum transfer compared to the wet clay. Thus, the ivory will rise higher after the collision.
