1. The problem statement, all variables and given/known data A 89.6 kg man steps off a platform 4.52 m above the ground. He keeps his legs straight as he falls, but at the moment his feet touch the ground his knees begin to bend, and, treated as a particle, he moves an additional 0.88 m before coming to rest. Treating our rigid legged friend as a particle, what is the average force his feet exert on the ground while he slows down? Note: Assume the acceleration while he is slowing down is constant. Give your answer in Newtons to the nearest whole number. Hint: Draw a free body diagram to aid in seeing the forces. 2. Relevant equations 4 equations of constant acceleration and F=ma 3. The attempt at a solution I was rather confused at the question's requirements to begin with, specifically with the terms 'average force' (I looked up average force to be only related to Δmomentum/Δtime, and this question is only with respect to "Newton's laws of motion") and "while he slows down". Any help would be greatly appreciated.
