Question

there is a massless rope that is pulled over a frictionless pulley that is suspended high above the ground one end of the rope is tied to a heavy block with a mass of 483 kg the free end is climbed by a person with a mass of 102 kg who starts from rest. If during the time of the person's climb they maintain a constant acceleration, and the normal force between the block and ground is 3000 N, how much time will it take for the person to climb a distance of 10.7 m up the rope?
