A car and a train are traveling along parallel roads at 18 m / s. The car stops with a smooth (constant) acceleration of -2.7 m / s ^ 2 due to the red light and waits still for 62 s after stopping. When the green light turns on, it reaches a speed of 18 m / s again with a smooth acceleration of 2.7 m / s ^ 2. Since the speed of the train did not change at all, how long did it lag behind the train when the car reached 18 m / s again?
