Calculate the impulse experienced when a 67kg person lands on firm ground after jumping from a height of 2.5m Express your answer using two significant figures. J470kgm/s Correct Correct answer is shown. Your answer 469kgm/s was either rounded differently or used a different number of signific Estimate the average force exerted on the person's feet by the ground if the landing is stiff-legged. With stiff legs, assume the body moves 1.4cm during impact [Hint. The average net force on her which is related to impulse, is the vector sum of gravity and the force exerted by the ground.] Express your answer using two significant figures. Incorrect; Try Again; 3 attempts remaining Part C Estimate the average force exerted on the person's feet by the ground if the landing is with bent legs. When the legs are bent, assume the body moves about 48cm during impact. Express your answer using two significant figures
