⇒E In downhill speed skiing a skier is retarded by both the air drag force on the body and the kinetic frictional force on the skis. (a) Suppose the slope angle is θ=40.0^∘, the snow is dry snow with a coefficient of kinetic friction μk=0.0400, the mass of the skier and equipment is m=85.0  kg, the cross-sectional area of the (tucked) skier is A=1.30  m^2, the drag coefficient is C=0.150, and the air density is 1.20  kg / m^3. (a) What is the terminal speed? (b) If a skier can vary C by a slight
