A car weighs 2200 lb and is traveling 100 mi/h on a race track that is on a 3% upgrade. The car is preparing to pass a slower car and its torque/engine speed curve is given by the equation, Me = 8ne -0.05n,² with Me in ft-lb and ne in revolutions per second. Drivetrain efficiency is 90%, drive axle slippage is 2%, wheel radius is 15 inches, frontal area is 22 ft2, the drag coefficient is 0.35, and air density is 0.0022 slugs/ft3. If the car isin a gear that produces maximum torque, what would the car's maximum acceleration be?

TRAFFIC AND HIGHWAY ENGINEERING

 

A car weighs 2200 lb and is traveling 100 mi/h on a race track that is on a 3% upgrade. The car is
preparing to pass a slower car and its torque/engine speed curve is given by the equation,
Me = 8ne -0.05n²
with Me in ft-lb and ne in revolutions per second. Drivetrain efficiency is 90%, drive axle slippage is 2%, wheel
radius is 15 inches, frontal area is 22 ft2, the drag coefficient is 0.35, and air density is 0.0022 slugs/ft3. If the
car isin a gear that produces maximum torque, what would the car's maximum acceleration be?
