Do you understand what acceleration means? Do you understand that the integral of acceleration is speed and the integral of speed is position? Do you understand that if you apply the same acceleration to two items that are a certain distance apart, they will remain that same distance apart all during the acceleration and after it is all over, they will still be the same distance apart although moving at some speed relative to their starting condition?
