    Answer:

    3 * 10³J/s

    Explanation:

    Given :

    Force applied, F = 300 N

    Distance, d = 30 m

    Time, t = 3 seconds

    Power, P = Workdone / time

    Recall :

    Workdone = Force * distance

    Workdone = 300 N * 30 m = 9000 Nm

    Workdone = 9 * 10³ J

    Power = (9 * 10³ J) / 3s

    Power = 3 * 10³J/s
