On a two lane road, car A is travelling with a speed of 36 km h^(-1), Two cars B and C approach car A in opposite directions with a speed of 54 km h^(-1). At a certain instant, when the distance AB is equal to AC, both 1 km B decided to overtake A before Cdoes. What minimum acceleration of car B is required to avoid and accident?
