A skier of mass 66 kg skis straight down a 11° slope at constant velocity. Draw a free-body diagram of the skier with the various external forces acting on her. Include the force of air resistance, which is directed opposite the velocity. (Do this on paper. Your instructor may ask you to turn in this work.)
I would include upward forces of wind resistance,surface resistance, vertical support from the slope, and gravity downward (which has a component down the slope and normal)
