On a two-ane 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) 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 minmum acceleration of car B is required to avoid an accident ?
