Asked by Corey

A person jumps from the roof of a house 3.0 m high. When he strikes the ground below, he bends his knees so that his torso decelerates over an approximate distance of 0.60 m. The mass of his torso (excluding legs) is 48 kg.

*How do I find the average force exerted on his legs by his torso during deceleration?
