Question: Jumping to the Ground a 75.O-kg man steps off a platform 3.10 m above the ground, he keeps his legs straight as he falls, but

Jumping to the Ground a 75.O-kg man steps off a platform 3.10 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 0.60 m before coming to rest.
(a) What is his speed at the instant his feet touch the ground?
(b) Treating him as a particle. What is his acceleration (magnitude and direction) as he slows down, if the acceleration is assumed to be constant?
(c) Draw his free-body diagram (see Section 4.6). In terms of the forces on the diagram, what is the net force on him? Use Newton's laws and the results of
(b) to calculate the average force his feet exert on the ground while he slows down. Express this force in newtons and also as a multiple of his weight.
