The drag force, Fd, imposed by the surrounding air on a vehicle moving with velocity V is given by Fd= Cd ApV²/2 where Co is a constant called the drag coefficient, A is the projected frontal area of the vehicle, and p is the air density. An automobile is moving at V = 30 miles per hour with C = 0.28, A = 24 ft², and p = 0.075 lb/ft³. Determine the force, in lbf, and the power, in hp, required to overcome aerodynamic drag.
