Q. An 81.9 kg man steps off a platform 3.35 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 0.76-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: Suppose the acceleration while he is slowing down is steady.
