A plastic ball and a clay ball are moving towards and strike with the same speeds. From which ball does the wall receive a greater momentum?
Asked by Shiladitya Biswas | 22 Jul, 2012, 05:31: PM
Expert Answer
The wall will recieve a grater force from the clay ball, due to its higher mass.
Assuming that both the balls come to rest after striking (for easier calculations), and thus the ball with more mass will have more momentuma and thus will transfer the whole momentum to te wall
