Stopping distance. A car is traveling on a horizontal road with speed v_0=13.9 m/s at the instant the brakes are locked, so the tires are sliding instead of rolling. Use the work-energy theorem to calculate the minimum distance the car can stop if the coefficient of kinetic friction \mu_k=0.7 between the tires and the road. B: A: 12 m 16 m C: 17.5 m D: 14 m. E: 23.7 m
