Physics · Engineering Mechanics
A lead ball with a certain velocity strikes a wall and falls straight down, whereas a rubber ball of the same mass and velocity strikes the same wall and rebounds. Select the correct reason from the following:
- 1The kinetic energy of both the balls remains completely conserved
- 2The change in momentum suffered by the rubber ball is less than that of the lead ball
- 3The change in momentum suffered by the rubber ball is more than that of the lead ball✓
- 4Both the balls undergo an equal change in momentum
Correct answer
The change in momentum suffered by the rubber ball is more than that of the lead ball
