A conveyor belt rises at a thirty degree angle. Its vertical hight measured from the ground is 20 ft (Sorry I can't seem to get the picture to work). A silo is discharging sand onto the begining of the conveyor belt at a rate of 360,000 lb/hr. An electric motor is atatched to the belt to keep the belt running at a speed of 3 ft/s. Determine the average power generated by the motor.
