Calculating the Force of Impact when Stepping off a Wall

By Flipping Physics, 08/25/2016

A 73 kg mr.p steps off a 73.2 cm high wall. If mr.p bends his knees such that he stops his downward motion and the time during the collision is 0.28 seconds, what is the force of impact caused by the ground on mr.p? Want lecture notes? This is an AP Physics 1 Topic.
