A 60-kg woman holds a 9-kg package as she stands within an elevator which briefly accelerates downward at a rate of a = 3.1 m/s². Determine the force N which the elevator floor exerts on her feet and the lifting force L which she exerts on the package during the acceleration interval. If the elevator support cables suddenly and completely fail, what values would N and L acquire? (N = 463 N, L = 60.4 N, N = L = 0) 9 kg a 60 kg
