A newly designed car has a 9.2 ft wheelbase, is rear wheel drive, and has a center of gravity 18 inches above the the road and 4.3 ft behind the front axle. the car weighs 2450 lb, the mechanical effciency of the drivetrain is 90%, and the wheel radius is 14 inches. the base engine develop 185 ft-lb of torque, and a modified version of engine develop 215 ft-lb of torque. if the overall gear reduction ratio is 9 to 1, what is the maximum accelaration from rest for the car with the 185 ft-lb engine and for the car with the 215 ft-lb engine?
