Q. A car is traveling at 61.6 km/hr on a flat, concrete highway. If the brakes are applied such that skidding occurs, the kinetic coefficient of friction between the road and tires is 0.802. If anti-lock brakes are properly applied then no skidding occurs and the static coefficient of friction is 0.992.
