The aerodynamic drag force Fd in kN on an automobile is given as Fd = 1/2000 cd

Question:

The aerodynamic drag force Fd in kN on an automobile is given as Fd = 1/2000 cd A ρ V2 [kN], Where cd is the non-dimensional drag coefficient, A is the frontal area in m2, ρ is the density of the surrounding air in kg/m3, and V is the velocity of air with respect to the automobile in m/s. Determine the power required to overcome the aerodynamic drag for a car with cd = 0.4 and A = 7 m2, traveling at a velocity of 100 km/h. Assume the density of air to be ρ = 1.2 kg/m3.
