1. The problem statement, all variables and given/known data An automobile and train move together along parallel paths at 38.9 m/s. The automobile then undergoes a uniform acceleration of −4 m/s2 because of a red light and comes to rest. It remains at rest for 71.7 s, then accelerates back to a speed of 38.9 m/s at a rate of 3.52 m/s2. How far behind the train is the automobile when it reaches the speed of 38.9 m/s, as- suming that the train speed has remained at 38.9 m/s? Answer in units of m. Ok i know that the total distance that the train covered in those 71.7s is 2789.13m now what else do i need to do to find out how far behind is the automobile? How can i tell the total distance traveled by the car? is it d = vi(t)+1/2a(t)^2?
