Homework Answers
There will be four force vectors in the
free-body diagram of the skier. The four forces are W
weight of the skier, N is the normal applied by the slope
on the skier, 
air
resistance (force applied by the air on the skier), and
Fk is the force of kinetic friction applied by
the slope on the skier. The free-body diagram of the skier is
Note that air resistance and the force of kinetic friction are acting opposite to the direction of the skier's velocity.

A skier going down a slope of angle θ below the horizontal is opposed by a...
A skier going down a slope of angle θ below the horizontal is opposed by a turbulent drag force that the air exerts on the skier and by a kinetic friction force that the snow exerts on the skier. The mass of the skier is m. Determine the terminal speed assuming that the coefficient of kinetic friction between the skis and the snow is μ, the density of air is ρ, the skier's frontal area is A, and the drag...

At constant velocity, a skier is making turns as he skis down a slope. If the coefficient of kinetic friction is 0.10, what is the total length of the skier’s tracks as he drops a vertical distance of 50.0 m down a 30°degree slope at constant velocity?
