During rush hour, cars back up when the traffic signal turns red. Assuming that the cars that lined up at the traffic signal are equally spaced (∆x) and the same length (L). You do not begin to move un3l the car in front of you begins to move, crea3ng a reac3on 3me (∆t) between the 3me the car infant begins to move and the you start moving. When you start moving, you immediately move at constant speed (v). If the traffic signal stays green for some 3me (tg), how many cars (N) will make it through the light? Use SOLVEM to analyse this problem, and create an expression that can be used to solve a specific question about the situation.
