A car has a mass of 1600 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 8000 N.  Draw a picture and identify all the forces acting on the car while the brakes are applied before it stops. Draw a free body diagram (FBD) of the car during this time. Don’t forget to label your coordinate system. If the car was initially moving at 20 m/s, what is the shortest distance in which the car can stop safely?
