The driver of a vehicle traveling at 118 kph at the top of a hill applies the brakes, causing the wheels to lock. The coefficient of friction between the tires of the vehicle and the rough surface of the road is u_s = 0.8 and u_k = 0.6. If the instantaneous radius of curvature of the vehicle's path is 0.25 km, what is the acceleration of the vehicle tangent to its path?
