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 5.2 m/s2; after 3.9 s he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant velocity of 71.1 m/s overtakes and passes the entering car. The entering car maintains its acceleration. How much time is required for the entering car to catch up with the other car?
