Two trains A and B of length \(400\) m each are moving on two parallel tracks with a uniform speed of \(72\) km/h in the same direction with A ahead of B. The driver of B decides to overtake A and accelerates by \(1\) m/s^{2}. If after \(50\) s, the guard of B just brushes past the driver of A, what was the original distance between them?

1. \(2000\) m

2. \(2250\) m

3. \(1200\) m

4. \(1250\) m

On a two-lane road, car A is travelling at a speed of \(36\) kmh^{-1}. Two cars B and C approach car A in opposite directions with a speed of \(54\) kmh^{-1} each. At a certain instant, when the distance AB is equal to AC, both being \(1\) km, B decides to overtake A before C does. What minimum acceleration of car B is required to avoid an accident?

1. \(1\) ms^{-2}

2. \(5\) ms^{-2}

3. \(2\) ms^{-2}

4. \(3\) ms^{-2}
