A car weighs 2200 lb and is travelling 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 (with Me in ft-lb and ne in revolutions per second): Me=8ne -0.05n.²; Drivetrain efficiency is 95%, drive axle slippage is 3%, wheel radius is 15 inches, frontal area is 22 ft², drag coefficient is 0.35, air density is 0.0022 slugs/ft³, and engine speed is 4800 rev/min. If the car is in a gear that produces maximum torque, what would the car's maximum acceleration be?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
