A woman (mass= 70.9 kg) jumps off of the ground, and comes back down to the ground at a velocity of -9.8 m/s.

If the woman lands completely stiff-legged, she will come to a stop in 0.009 s.

Find the magnitude of the force on the woman during this time she comes to a stop.

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

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
