Assuming the car starts from rest, how far does the car travel in 5 seconds? Solution Car at t = 0 and t = 5 seconds. Since distance is needed, the acceleration equation must be integrated twice. First, find the velocity function, Notice, the integration was done with time, t, and not 5 seconds. Since the velocity at 5 seconds is not requested, only the general velocity function is determined. Next, find the distance traveled in 5 seconds by integrating the velocity function that was just determined, The final position after 5 seconds is x = (625 + 125) / 6 = 125 m
