During an experiment investigation of the effect on an athlete's feet and legs when jumping and landing on a hard floor a 65 kg person steps off a platform that is located 1 m above a hardwood floor. She lands on both feet and it is determined that it took 150 ms from the instant that her feet hit the floor for her body to come to a stop. You may ignore air resistance in your analysis of this problem.

A.) How much time does it take from when she leaves the platform until her feet make contact with the floor?

B.) How fast is she moving as her feet make contact with the floor?

C.) Calculate her acceleration during the time that it takes for her to come to a stop?

D.) How much force acts on each of her feet while she is coming to a stop?
