A movable pulley supports a load of \(200\ \text{N}\). The rope passes over a frictionless fixed pulley and is pulled by a person at constant speed. The movable pulley has an efficiency of 85 % because of bearing friction. (a) What is the tension in each rope segment that directly supports the load? (b) What force must the person apply to the free end of the rope? (c) If the person pulls the rope with a speed of \(0.50\ \text{m\ s}^{-1}\), what is the mechanical power output of the system? Give your answers to three significant figures.
