VIDEO TRANSCRIPT

Power equals work divided by time, and we'll solve for work by multiplying both sides by time. And then that gives us the work is power multiplied by time. We know this motor is 3 Horse powers. We'll have to change that into Watts. We have 746 Watts per Horse power, and these Horse powers we'll end up canceling, giving us the power in Watts, times 1 hour, and converting that into seconds, because we always need Mks units, almost always. And these hours cancel giving us seconds there. And you multiply through and you end up with 8.1 times 10 to the 6 Joules.
