Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

On a level test track, a car with anti locks brakes and 90% braking efficiency is determined to have a theoretical stopping distance (ignoring aerodynamic resistance) of 408-ft (after the brakes are applied) from 100-mi/h. The car is rear-wheel drive with a 110-inch wheel base, weighs 3200-lb, and has a 50/50 weight distribution (front to back), a center of gravity that is 22-inches above the road surface, an engine that generates 300-ft lb of torque, an overall gear reduction of 8.5 to 1 (in first gear), a wheel radius of 15-inches and a driveline efficiency of 95%. What is the maximum acceleration from rest of this car on this test track? Thank you for helping.
