A car traveling at 30 m/s is at the top of a hill. The coefficient of kinetic friction between the tires and the road is μk = 0.8. The instantaneous radius of curvature of the car s path is 200 m. If the driver applies the brakes and the car’s wheels lock, what is the resulting deceleration of the car in the direction tangent to its path?
