Problem a 540-g super ball traveling at 290 ms bounces off, Ask an Expert

Academics

Problem: A 54.0-g Super Ball traveling at 29.0 m/s bounces off a brick wall and rebounds at 18.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.00 ms,

A- What is the magnitude of the average acceleration of the ball during this time interval?

It'd be really helpful if you could show all steps of your work.
