Question : A metal ball and a rubber ball, both having the same mass, strike a wall normally with the same velocity. The rubber ball rebounds and the metal ball does not rebound. It can be concluded that:
Option 1: The rubber ball suffers a greater change in momentum
Option 2: The metal ball suffers a greater change in momentum
Option 3: Both suffer the same change in momentum
Option 4: The initial momentum of the rubber ball is greater than that of the metal ball
Correct Answer: The rubber ball suffers a greater change in momentum
Solution : The correct option is The rubber ball suffers a greater change in momentum .
When a metal ball and a rubber ball of the same mass hit a wall with the same velocity, the rubber ball rebounds while the metal ball doesn't. This happens because the rubber ball changes direction and experiences a greater change in momentum.
