The drag coefficient Cd is a number with no units. It is used to compare the drag on different cars at different speeds. Cd is given by the equation Cd = AvFnρ2 where F is the drag force on the car, ρ is the density of the air, A is the cross-sectional area of the car and v is the speed of the car. What is the value of n?
