Skier on a slope (Fnormal, Ffriction, etc)

    1. The problem statement, all variables and given/known data

    A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 30.9 ° 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 61.4 kg, and the coefficient of kinetic friction between the skis and the snow is 0.116. Find the magnitude of the force that the tow bar exerts on the skier.

    2. Relevant equations


    3. The attempt at a solution

    so is it the tow bar force = force of friction? the answer is just u times horizontal component of gravitational force?

    or was it u times normal force? 61.4*9.8cos30.9*.116=59.8925 N?
