A 3000-lb car has a maximum speed (at sea level and on a level, paved surface) of 140 mi/h with 16-inch-radius wheels, a gear reduction of 3.5 to 1, and a drivetrain efficiency of 92%. It is known that at the car's top speed the engine is producing 220 ft-lb of torque. If the car's frontal area is 25 ft 2 , what is its drag coefficient?
