A 50.0 g Super Ball traveling at 25.0 m/s bounces off a brick wall and rebounds at 21.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 5.00 ms, what is the magnitude of the average acceleration of the ball during this time interval? (Note: 1 ms = 10-3 s.)
a=change in velocity/change in time
What I did so far was (21-25)/0.005=-800 m/s^2
however this wrong, not sure why though. Could someone explain why my attempt is wrong
