    F = 600 N, the applied force

    a = 0.08 m/s², the acceleration

    t = 1 min = 60 s, the duration

    Calculate the distance traveled.

    s = (1/2) at²

    = 0.5 * (0.08 m/s²) * (60 s) ²

    = 144 m

    Because the force remains constant, the work done is

    W = f*s

    = (600 N) * (144 m)

    = 86400 J

    The average power is

    Pavg = (86400 J) / (60 s) = 1440 W

    Answer: 1440 W
