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 6.8 m/s2; after 4.1 s he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant velocity of 66.0 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? b.2 Equations used v2=u2+2as s=ut+1/2at2 and other equations 3. The attempt at a solution distance = v2=u2+2as s= v2 - u2/2a s= 263.1m The answer is t = 11.2s .... I am really stuck guys. I understand the final velocity of the entering car must be greater to catch up to the car travelling constant acceleration, but the displacement is the same. But I am finding it difficult to proceed without knowing the final velocity of entering car or the displacement. Can someone offer a worked example for me - with different values?
