    100 Watts

    Explanation: Power is the rate at which work is done. Power is measured in Joules per second or watts. It is calculated by dividing work done in joule by time taken in seconds.

    Power = Work done : time

    In this case;

    Work done = 10,000 Joules

    Time = 100 sec

    Therefore;

    Power = 10,000 Joules : 100 sec

    = 100 J/s

    Therefore, the power of the crane is 100 watts
