The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaÏv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and Ï is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and Ï = 1.2 kg/m3.
