Consider two tennis balls. When dropped from shoulder height, ball 1 hits the floor and rebounds to 80% of its original drop height. When dropped from shoulder height, ball 2 hits the floor and stops. In the collision with the floor, which ball receives the greater impulse?
A: Ball 1, because the impulse is about double that received by ball 2
B. Ball 1, because the impulse received by ball 2 is about zero
C. Ball 2, because the impulse received by ball 1 is about zero
D. Ball 2, because the time of interaction at the floor is very small
I thought that impulse=FdeltaT, so if the time of the collision is longer, the impulse is higher? Since ball 2 sticks to the ground, isn't it's T larger than Ball 1?
Also, how do you know that Ball 1's impulse is double that of Ball 2?
