While visiting a friend in San Francisco, you decide to drive around the city. You turn a corner and find yourself going up a steep hill. Suddenly a small boy runs out on the street chasing a ball. You slam on the brakes and skid to a stop, leaving a skid mark 50 ft long on the street. The boy calmly walks away, but a policeman watching from the sidewalk comes over and gives you a ticket for speeding. You are still shaking from the experience when he points out that the speed limit on this street is 25 mph. After you recover your wits, you examine the situation more closely. You determine tha tthe street makes an angle of 20 degrees with the horizontal and that the coefficient of static friction between your tires and the street is .80. You also find that the coefficient of kinetic friction between your tires and the street is .60. Your car's information book tells you that the mass of your car is 1750 kg. You weight 130 lbs. Witnesses say that the boy had a weight of about 60 lbs. and took 3 seconds to cross the 15 ft wide street. Will you fight the ticket?
