A 1.7 kg ball strikes a wall with a velocity of 7.7 m/s to the left. The ball bounces off with a velocity of 6.5 m/s to the right. If the ball is in contact with the wall for 0.17 s, what is the constant force exerted on the ball by the wall?

Answer 1

force*time=changeinmomentum=1.7kg*(6.5-(-7.7)) ?

solve for force.
