The drag coefficient $$\(C_{d}\)$$ is a number with no units. It is used to compare the drag on different cars at different speeds. $$\(C_{d}\)$$ is given by the equation $$\[ C_{d}=\frac{2 F}{v^{n} \rho A} \]$$ where $$\(F\)$$ is the drag force on the car, $$\(\rho\)$$ is the density of the air, $$\(A\)$$ is the cross-sectional area of the car and $$\(v\)$$ is the speed of the car. What is the value of $$\(n\)$$ ?
