A skier of mass 64 kg skis straight down a 12 degree 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. (a) Find the value of the normal force. (b) The force of air resistance has a magnitude of 75 N. Find the frictional force on the skis. (c) What is the coefficient of kinetic friction?
