A 50.0-g superball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. A high-speed camera records the event. If the ball is in contact with the wall for 3.50 ms, what is the magnitude of the average acceleration of the ball during this time interval? (note: 1 ms= 10^-3 s.)© BrainMass Inc. brainmass.com February 24, 2021, 2:13 pm ad1c9bdddf
This is a fairly simple problem but there are a couple of "tricky" things that to which you should pay attention. I'll mention them as you go along.
First of all, the basic concept is average acceleration is equal to change in velocity over change in time.
The solution explains and solves the problem.
