A student, late for class, ran up some stairs
between landings. The landings are 8.2 m
apart. The student has a mass of 54.1 kg and
it took 7 s to do the run.
The acceleration of gravity is 9.8 m/s
What is the average power that the student
was generating during the run?

    P = M g H/t

    H = 8.2 m
    g = 8.81 m/s^2
    t = 7.0 s
    M = 54.2 kg

    The answer will be in watts.
