A 74.1 kilogram person steps off a platform 3.12 meter 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 0.610 meter before coming to rest.
Part A. Find his speed at the instant his feet touch ground?
Part B. Treating him as a particle, find the magnitude of his acceleration as he slows down if the acceleration is constant?
Part C. Treating him as a particle, find the direction of his acceleration as he slows down if the acceleration is constant?
Part D. Find the magnitude of the reaction force to the force you found in part E?
Part E. Find the direction of the reaction force to the force you found in part E?
