A race driver has made a pit stop to refuel. After refueling, he starts from rest and leaves the pit area with an acceleration whose magnitude is 5.5 m/s2; after 4.1 second he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant velocity of 68.6 meter per second overtakes and passes the entering car. The entering car maintains its acceleration. Find how much time is required for the entering car to catch up with the other car?
