A 0.140kg baseball traveling 38.0m/s strikes the catcher's mitt, which, in bringing the ball to rest, recoils backward 15.0cm .What was the average force applied by the ball on the glove?

change of momentum = .14 * 38
average speed during stop = 38/2 = 19
time to stop = t =.15/19 = .00789 seconds
F = change in momentum/time = .14*38/.00789
= 674 Newtons
