## Homework Statement

Jeff Gordon (a race-car driver) discovers that he can accelerate at 4.0m/s

^{2}without spinning his tires, but if he tries to accelerate more rapidly he always "burns rubber."

Find the coefficient of friction between his tires and the road. Assume the force from the engine is applied only to the rear tires.
