There is no one around to help, so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley You pull up on the rope to lift the box. (Figure 1) Part A Once you have pulled hard enough to start the box moving upward, what is the magnitude F of the upward force you must apply to the rope to start raising the box with constant velocity? Use g for the magnitude of the acceleration due to gravity and neglect friction forces. Express the magnitude of the force in terms of m, the mass of the box.
