During the 18.0-m displacement, the normal force exerted by the elevator floor does 8.25 kJ of work on her and gravity does - 7.35 kJ of work on her. Part A What is the mass of the woman? WebJan 1, 2004 · The force exerted by the floor on the girl is usually called the normal force, N. Since the system is stationary, its acceleration is 0. Using F net = ma (Netwon's second law), we see that the vector sum of the forces must be 0 (the forces balance out). You would use that if you wanted to find out the value of the normal force (N-mg = 0). family guy hefty hefty hefty
