    Answer: 48.08 watts

    Explanation:

    power needed = ?

    Work done = 462 joules

    Time taken = 9.61 seconds

    Recall that power is the rate of energy expended or workdone per unit time. i. e Power = Workdone / Time

    Power = 462 joules / 9.61 seconds

    Power = 48.08 watts

    Thus, 48.08 watts of power is needed to the work.
