A car is traveling on a level road with speed v_o at the instant when the brakes lock (preventing tire rotation) so that the tires slide rather than roll.
A. Use the work-energy theorem to calculate the minimum stopping distance of the car in terms of v_o, g, and the coefficient of kinetic friction, mu_k between the tires and the road.
B. The car stops in a distance of 91.9 m if v_o = 80km/h. What is the stopping distance is v_o = 60 km/h? (Assume that the value of mu_k remains the same).
