The drag force, Fd, imposed by the surrounding air on a vehicle moving with velocity V is given by F= C₁ ApV²/2 where Ca 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 = 50 miles per hour with Cd = 0.28, A = 26 ft², and p = 0.075 lb/ft³. Determine the force, in lbf, and the power, in hp, required to overcome aerodynamic drag. Step 1 * Your answer is incorrect. Determine the force, in lbf, required to overcome aerodynamic drag. Fd=91.25 lbf
