A 72-kg woman holds a 6-kg package as she stands within an elevator which briefly accelerates upward at a rate of 0.28g. Determine the force R 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 R and L acquire? 6kg 0.28g 72kg Answers: While accelerating, R= i N L = i N After the cables fail, R= i N L= i N 1
