A car with a mass of m1864 kg travels along a flat, horizontal road with a speed v;58 km/h. At t = 0 it sees a child ahead and slams on its brakes. Its wheels lock in place and it skids along the road. The coefficient of kinetic friction between the wheels and the road is0.29. What is the momentum of the car before it hits its brakes? Once the car has slammed on its brakes what is the magnitude of the frictional force acting on it? What distance will the car travel after stepping on the brakes?
