Problem: A 51.5-g Super Ball traveling at 29.5 m/s bounces off a brick wall and rebounds at 19.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.20 ms,
Part A: What is the magnitude of the average acceleration of the ball during this time interval?
I need help to find the magnitude of the average acceleration of the ball during this time interval.
