Asked by Arlin
Suppose a bouncy ball were thrown against a wall. The ball hit with 15 m/s and then bounced backwards with 15 m/s. The interaction time with the wall was 0.5 ms (5 x 10-3 s). If the ball's mass is 0.1 kg, what is the average force of the wall on the ball?

due to changing directions, the change in momentum is (mass(vf-vi))=.1kg*(30m/s)
force*time=changeinmomentum
force*time=changeinmomentum
