A skier of mass 65.0 kg is pulled up a slope by a motor-driven cable. How much work is required to pull the skier 57.0 m up a 35° slope (assumed to be frictionless) at a constant speed of 2.0 m/s?

    The vertical rise is
    H = 57 sin 35 meters.

    The work required to raise the skier that amount is M g H.

    It does not depend upon the speed, although the required power does.
