A woman (mass= 50.5 kg) jumps off of the ground, and comes back down to the ground at a velocity of -8.4 m/s.
Rather than landing stiff-legged, it would be much safer for the woman to land with bent knees, which would bring her to a stop in about 0.27 seconds. Show the average net force that would act on her with this longer stopping time.
Hint: You will need to find the change in the woman's momentum before and after she lands, and set that equal to our impulse formula ( p = F*t) to find the average force during the impact
