For a summer job you take a position as an accident investigator for your local police force. On your first day you are called to the scene of a possibly minor accident at a large intersection with a 4-way stop. From the positions of the cars you can see that driver A was traveling northward in a small car and driver B was traveling eastward in a car that looks like it has approximately twice the mass of car A. The debris from their collision is in the center of the intersection. You can see the 5 m long marks left by the skidding tires that lead from the impact point to where the cars now rest, stuck together. The skid marks point in a direction 18.4˚east of north. From your measurements of the marks and from knowing something about the frictional force of asphalt on tires, you estimate that the cars were moving about 20 miles per hour immediately after the collision. Driver A says that driver B ran through a stop sign. Driver B says the opposite. You determine the speeds that each driver was traveling to help determine who is at fault. Make sure that y explain clearly how you determined the speeds of each car.
