A car has a 10-ft wheelbase (L). the center of gravity is 18 inches about the ground and 5 ft behind the front axle. The weight of the car is 2500 lb. mechanical efficiency if the drivetrain is 85%. and the wheel radius is 15 inches. The engine of the car develops 200 ft-lb of torque. the overall gear reduction ratio is 8 to 1.
(a) if the car is front-wheel drive. what is the maximum acceleration from rest of the car on good, wet and level pavement?
(b) if the car is rear-wheel drive what is the maximum acceleration from rest of the car on good, dry pavement with a 5% upgrade slope?
