A 0.291 kg rubber ball is dropped from a height of 3.72 m, and it rebounds to a height of 2.88 m. Assume there is no air friction.
a) Find the magnitude of the impulse exerted by the ground on the ball.
The Attempt at a Solution
I used Kinematic equations to find out the the Vf down of the ball was 8.54
and then Vavg=4.27... MVdown=1.242
MVdown-MVup = Impulse
MVup i did the same thing i got 1.093
Ended up wrong
Thank you for your help
