Car A moves at a constant velocity of 72 km/h and passes Car B, which is at rest. At this point, Car B accelerates at 10 ms^-2 and overtakes Car A after t amount of time.
1. Find t
2. Find the displacement of both cars at t
3. State the acceleration needed by Car B to overtake Car A with only (t-2) seconds
