1. The problem statement, all variables and given/known data A 55 kg woman jumps to the floor from a height of 1.5 m. If her body comes to rest during a time interval of 8.00 * 10^-3 seconds, what is the force of the floor on her feet? 2. Relevant equations Unit conversion and g = 9.8m.s^2 ~ 10 m/s^2 3. The attempt at a solution The way I understand it, she is at rest, so Fnet = 0 Fnormal - Fg = 0 Fnormal = Fg = mg = 550 N This is wrong, and the answer is around 300 N. Why is this?
