A car is traveling at 30 mph on a good, dry pavement at sea level. The front-wheel-drive car has a drag coefficient of 0.35, a frontal area of 30 ft2 and a weight of 2500 lbs. The wheelbase is 120 inches and the center of gravity is 20 inches from the ground, 50 inches behind the front axle. The engine is producing 100 ft-lbs of torque and is in a gear that gives an overall gear reduction ratio of 4.5. The radius of the drive wheels is 15 inches and the mechanical efficiency of the drivetrain is 95%. What is the maximum acceleration that the car can achieve?
