A 64-kg woman holds a 7-kg package as she
stands within an elevator which briefly
accelerates upward at a rate of 0.29g.
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?
