The drag force, Fd, imposed by the surrounding air on an
automobile moving with velocity V is given by Fd = Cd A½ ρV2 where
Cd is a constant called the drag coefficient, A is the projected
frontal area of the vehicle, and ρ is the air density. For Cd =
0.43, A = 2.51 m2, and ρ = 1.01 kg/m3, calculate the power required
in kW to overcome drag at a constant velocity of 101.55 km/h.
