A 71-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? Answers: 6kg 71kg While accelerating, R = After the cables fail, R = 0.28g i i N L= N L= i i N N
