    Answer: 66.7 watts

    Explanation:

    Given that:

    Work performed by man = 200 j

    Time taken to do work = 3 seconds.

    Power = ?

    Recall that power is the rate of work done per unit time

    i.e Power = work/time

    Power = 200J / 3seconds

    Power = 66.7 watts

    Thus, his power is 66.7 watts
