A particular hydraulic pile driver uses a ram with a mass of 1,200 kg. If the maximum pile energy is 12,780 J, how high must the ram be raised to achieve this value? m Assuming it takes 0.72 s for the pile driver's winch motor to raise the ram at a constant speed to this height, what is the power output by the motor in completing this task? Express your answer in both watts and horsepower.

power in watts	W
power in horsepower	hp
