You are driving your car uphill along a straight road. Of Suddenly, you see a car go through a red light and enter the intersection, just ahead of you. you. You immediately apply your brakes and skid straight to a stop, leaving a 100 ft long mark from the landslide. A policeman observes the whole incident, give the driver of the car a ticket for running a red light. He also gives a ticket to you for exceeding the 30 mph speed limit. When you get home, you read your physics book and you may notice that the coefficient of kinetic friction between the tires and the road was 0.60, and the coefficient of static friction was 0.80. You estimate that the hill makes an angle of about 10° with the horizontal. Check the manual owner and find that your car weighs 2,050 lbs. Are you going to claim the traffic ticket? in the court?

How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in Figure 3.58, then this problem asks you to find their sum R=A+B.)

You are a construction worker standing still on 12th Ave N in Fargo, and you watch a minivan drive past at 25 mi/hr eastward. A kid in the back throws a ball at his brother in the front seat at 19 mi/hr. How fast does the ball move, as observed by you? (Positive indicates east, negative indicates west.) ? How fast does the ball move, according to the kid who threw it? If instead the kid in the front seat throws a rock at the kid in the back seat at 19 mi/hr, how fast would you observe the rock to travel?
