Solve the following problem:
Problem: A 50.5-g Super Ball traveling at 29.5 m/s bounces off a brick wall and rebounds at 21.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.25 ms, what is the magnitude of the average acceleration of the ball during this time interval?
Please show the work for the calculation so I can understand what I'm doing. Thanks!
