Arear-wheel–drive car weighs 2600 lb and has an 84-inch wheelbase, a center of gravity 20 inches above the roadway surface and 30 inches behind the front axle, a drivetrain efficiency of 85%, 14-inch–radius wheels, and an overall gear reduction of 7 to 1. the car's torque/engine speed curve is given by the equation me=6ne−0.045ne2. if the car is on a paved, level roadway surface with a coefficient of adhesion of 0.75, determine its maximum acceleration from rest.
