How much work does a 120 pound boy do in climbing to the top of the Washington Monument - a climb of 550 feet? If the climb in problem 2 takes 20 minutes, what is the average horsepower produced by the boy?

    This is a physics question, not a math question, although you need to use math to soilve it.

    The work done is 120 x 550 foot-pounds.

    Divide that by the time required (in seconds) to get the power in ft-lb per second.

    Then use the conversion factor for horsepower.
    1 horsepower is defined as 550 foot-pounds per second

    You may be surprised at the answer.
