A van travels on a rough level road with an initial speed vo. The road has a coefficient of kinetic friction Hk. At the instant when the brakes lock, the tires slide than roll. 1. List down the forces that do work on the car. 2. Use the work-kinetic energy theorem to determine the minimum stopping distance of the car in terms of its initial velocity vo, the acceleration due to gravity g and the coefficient uk. 3. Using one of the kinematic equations, determine the time it takes for the car to stop in terms of the initial velocity vo. 4. Use your previous result to determine the power it takes for the car to stop completely.
