A car is travelling 50mi/hr on a good, wet, level road. The car weighs 3200 lIbs, has Cp=0.35, A=20ft, and a gear reduction ratio of 5 to1. The air density is 0.002045 slugs/ft° and the car is producing 150 ft.lb of torque, with a wheel radius of 14 inches, and a mechanical efficiency of the drive train is 80%. The wheelbase is 100 inches, the center of gravity is 20 inches above the road surface and 50 inches behind the front axle. What is the acceleration if the car is front wheel drive?
