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 3.7 m/s2 for 4.5 seconds. it then continues at a constant speed for 8.6 seconds, before applying the brakes such that the carâs speed decreases uniformly coming to rest 229.73 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.(a) how fast is the blue car going 3.6 seconds after it starts? (b) how fast is the blue car going 8.8 seconds after it starts? (c) how far does the blue car travel before its brakes are applied to slow down?
