Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 3 m/s2 for 3.6 seconds. It then continues at a constant speed for 11.5 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 171.05 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the blue car comes to a stop.
