A hard rubber ball is bounced on the floor. Compare the ball's acceleration on the way down to its acceleration on its way back up.
3. The Attempt at a Solution [/b
First off, ignore air resistance.
Lets assume that the person bouncing the ball uses some force and doesn't just drop the ball. This would mean that the acceleration of the ball would be
Initial force used + 9.8m/s^2, correct?
The bounce would absorb some of the initial force, but no all of it, correct?
The gravitational pull would be symmetrical so the end result would be
(Initial force - absorbed from bounce) + 9.8m/s^2, correct?
