8. In order for an empty elevator with a balancing weight to move up at a constant velocity of 2.2 m/s, the motor has to provide 220 W. (a) What is the magnitude of the frictional forces that opposes the motion of the elevator? (b) Three people, whose total mass are 240 kg, entered the elevator on its way up. What was the power provided by the motor as the elevator was moving at 2.2 m/s? (c) If the maximum power that the motor can provide during the cruising phase is 1.5 horsepower, what is the maximum load that can be lifted at a speed of 2.2 m/s?
