The drag force, FD, imposed by the surrounding air on a vehicle moving with velocity V is given by
where CD is a constant called the drag coefficient, A is the projected frontal area of the vehicle, and is the air density. Determine the power, in kW, required to overcome aerodynamic drag for a truck moving at 110 km/h, if CD 0.65, A 10 m2 , and 1.1 kg/m3
