(a) Calculate the impulse experienced when a 65-kgperson lands on firm ground after jumping from a height of3.0 m. (ib) Estimate the average force exerted on thepersons feet by the ground if the landing is stiff-legged, andagain (c) with bent legs. With stiff legs, assume the bodymoves 1.0 cm during impact, and when the legs are bent,about 50 cm. [Hint: The average net force on her which isrelated to impulse, is the vector sum of gravity and theforce exerted by the ground.]
