# 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
