The drag force, Fd, imposed by the surrounding air on a
vehicle moving with velocity V is given by
Fd 5 CdA12
rV2
where Cd is a constant called the drag coefficient, A is the
projected frontal area of the vehicle, and r is the air density.
Determine the power, in hp, required to overcome aerodynamic
drag for an automobile moving at (a) 25 miles per hour,
(b) 70 miles per hour. Assume Cd 5 0.28, A 5 25 ft2, and r 5
0.075 lb/ft2.
