A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 21.5 ° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 55.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.212. Find the magnitude of the force that the tow bar exerts on the skier.

    Mass = 55.0 kg

    Coefficient of friction = 0.212

    Slope = 21.5 degrees

    Gravity = 9.81

    Magnitude of force = 55*9.81 * (0.212*cos21.5 + sin21.5)

    Magnitude of force = 304.17 Newtons

    Round the answer as needed.
