change in velocity/change in time
= (15.5 +29.5)/5*10^-3
if the second part asks for the average force, multiply by the mass
A 47.0-g Super Ball traveling at 29.5 m/s bounces off a brick wall and rebounds at 15.5 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?
