Speeding ticket? You are driving your car uphill along a straight road. Suddenly you see a car run a red light and enter the intersection just ahead of you. You slam on your brakes and skid in a straight line to a stop, leaving skid marks 5 feet long. A policeman observes the whole incident and, much to your shock, gives you a ticket for exceeding the speed limit of 80 mph. When you get home, you consult your Physics notes and estimate that the coefficient of kinetic friction between your tires and the road was 2 and the coefficient of static friction was 1. You estimate that the hill made an angle of 40 degrees with the horizontal. You look up in your owner's manual and find that your car weighs 3000 lb. Will you fight the traffic ticket in court?
