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...
