You are stopped at a red light, waiting for it to turn green. At the instant the light turns green, a truck in the next lane passes you, traveling at a constant velocity of 15 m/s. One second later, you begin accelerating with a constant a = 6.0 m/s^2. (1) How much time does it take for you to catch up to the other car?
