    Answer: 600watts

    Explanation:

    Power of crane = ?

    Work done by crane = 15000 J

    Time taken = 25s

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

    i.e Power = work/time

    Power = 15000J/25seconds

    Power = 600watts

    Thus, the power of the crane is 600watts
