A truck is subject to a drag force, Fd, from the surrounding air: where Cd = 0.28 is the drag coefficient, A = 30 ft2 is the area of the front of the vehicle, and r = 0.075 lb/ft3 is the density of the air. How much power (in hp) is required to overcome drag if the truck is traveling at v=65 miles/hr? If the truck maintains a constant velocity, how much work (Btu) does the truck require for a 1-hour trip?
