forces opposing the motion

(CD-ROM)

The two major forces opposing the motion of a vehicle moving on a level road are the rolling resistance of the tires, Fr, and the aerodynamic drag force of the air flowing around the vehicle, FD, given respectively by

where f and CD are constants known as the rolling resistance coefficient and drag coefficient, respectively, and A are the vehicle weight and projected frontal area, respectively, V is the vehicle velocity, and is the air density. For a passenger car with w = 3550 lbf, A = 23.3 ft2 , and CD = 0.34, and when f = 0.02 and ρ = 0.08 lb/ft3 , determine the power required, in hp, to overcome rolling resistance and aerodynamic drag when V is 55 mi/h.
