A fully loaded, slow-moving freight elevator has a cab with a total mass of 1300 kg, which is required to travel upward 47 m in 4.6 min, starting and ending at rest. The elevator's counterweight has a mass of only 990 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?
