What is maximum acceleration from rest for car with engine

Reference no: EM13307003

A newly designed car has a 9.0-ft wheelbase, is rear-wheel drive, and has a center of gravity 18 inches above the road and 4.3 feet behind the front axle. The car weights 2450 lb, the mechanical efficiency of the drivetrain is 90%, and the wheel radius is 14 inches. The base engine develops 200 ft-lb of torque, and a modified version of the engine develops 240 ft-lb of torque. If the overall gear reduction ratio is 8 to 1, what is the maximum acceleration from rest (in ft/sec^2) for:

a) the car with the base engine?

b) car with the modified engine?

Assume the car is on good dry pavement.
