Q. A 59kg woman trips while walking down the street. She stumbles forward and falls onto her outstretched right hand. At the instant her hand contacts the ground her whole body is moving downward at a velocity of 9m/s and has a downward acceleration of 9.8m/s^2 (gravity). Her body fast decelerates after contacting the ground; after 0.1s it has stopped moving.

Part A:
Assume her entire body mass is halted in 0.1s, how much force did her hand experience?

While she hit the ground with her hands, her wrist was extended at 45° and her elbow was bent 45°. The length is 27 cm and her upper arm is 32 cm.

Part B:
Assume the ground reaction force is acting directly vertically at the wrist, what is the moment about her elbow?
