1. The problem statement, all variables and given/known data Pat Summit (60 kg) is standing in an elevator which has a velocity of 10.0 m/s downward and an acceleration of 5.00 m/s^2 upward. What is the magnitude of the force exerted by the floor of the elevator on her? Is the elevator speeding up or slowing down? 2. Relevant equations F=ma.. 3. The attempt at a solution I really am not sure where to start here.. I drew a free body diagram but, does acceleration count as a force? How does velocity come into play?
