A man 1 of mass m strands on an elevator moving with upward acceleration a. A man(2) is standing on the elevator. Elevator starts with initial velocity v0 at time t=0. Consider time interval t from beginning. a. What is the work done by normal contact force and gravity on the man(1) as observe by man(2) standing on the elevator and man(3) standing on ground? b. What is the net work done by normal contact force between man(1) and elevator?
