A basketball player drops a 0.60-kg basketball vertically so that it is traveling at 6.0 m/s when it reaches the floor. The ball rebounds upward at a speed of 4.7 m/s.

Determine the average net force that the floor exerts on the ball if the collision lasts 0.12 s.

I calculated delta p= 6.42 kg.m/s

I thought average net force was delta p / delta t but the that is not right.

Please help! Thank you
