An 82 kg skier travels down a 17 degree slope at constant velocity as friction and 140 N of air/wind resistance act against the skier and skis. What is the coefficient of friction between the skis and snow?

Hello atomvik

Well : what have you tried so far to answer this question, your homework (most probably) ?

I suggest you take the slope and calculate the horizontal and vertical forces caused by speed, weight, and add the force caused by resistance. Remember it is given that the speed is and remains constant.
So your horizontal resistance force is compensated by the total vertical force (gravity).
