Question: A 53.5-g Super Ball traveling at 27.0 m/s bounces off a brick wall and rebounds at 19.0 m/s. A high-speed camera records this event.
Part A: If the ball is in contact with the wall for 4.05 ms, what is the magnitude of the average acceleration of the ball during this time interval?
Please show how you obtained the answer for above question.
