The Problem During rush hour, cars back up when the traffic signal turns red. Assume: cars lined up at a traffic signal, are equally spaced (Ax) and the same length (L); you do not begin to move until the car in front of you begins to move, creating a reaction time (At) between the time the car in front begins to move and the time you start moving; and when you start to move, you immediately move at a constant speed (V). If the traffic signal stays green for some time (tg), how many cars (N) will make it through the light? What you need to do (Instructions) Use SOLVEM to analyse this problem, and create an expression that can be used to solve a specific question about the situation
