Asked by Angie
A 500 g ball moving to the right at 9.2 m/s hits a wall and bounces in the other direction with a speed of 4.9 m/s. If the ball experiences an average force of 110 N during the impact with the wall, for how long is the ball in contact with the wall?

f = m a ... 110 = .5 a
a = Δv / Δt
110 = .5 (9.2 + 4.9) / t
a = Δv / Δt
110 = .5 (9.2 + 4.9) / t
