A 2500-lb car is traveling at a sea level on a good, dry road with CD = 0.35 and frontal area 21 ft2. Its engine is running at 2400 rev/min. The car's gear reduction ration is 4.5 to 1, drivetrain efficiency is 90%, drive axle slippage is 3%, and the road-wheel radius is 14 inches. What will the car's maximum acceleration rate be on a level road if the engine torque follows the equation Me = 8ne – 0.08ne2, where ne represents the number of revolutions per second for the engine? Assume that the available tractive effort is the engine-generated tractive effort.
