I've been working on it since yesterday. And i can't seen to get it right:
A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 26.0° 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 60.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.130. Find the magnitude of the force that the tow bar exerts on the skier.
I calculated the following:
(.13)(60)(9.8)cos(26) but that was wrong
then i tried (.13)(60)(9.8)sin(26) but that was wrong too. Any advice?
