A 855 kg car driving at an initial speed of 22.5 miles/hour on a horizontal road accelerates to 43.7 miles/hour over a distance of 77.6 feet. This turns out to be the fastest the car can accelerate without the wheels slipping on the road (i.e., "burning out"). What is the coefficient of static friction between the wheel and road surfaces ? You should compute this using energy conservation (since the wheels don't slip), then double check your answer using Newton's Laws and kinematic equations.
