a fully loaded, slow-moving freight elevator has a cab with a total mass of 1170 kg, which is required to travel upward 57 m in 3.3 min, starting and ending at rest. the elevator's counterweight has a mass of only 955 kg, and so the elevator motor must help. what average power is required of the force the motor exerts on the cab via the cable?
