In a GT car racing, a Porsche 919 (A) and an Audi R18 (B) reach the line C-C side by side at the same time. At line C-C, car A has a speed of 105 km/h while car B has a speed of 95 km/h. If car A maintains its speed when taking the curve, i) How fast should car B accelerate to reach the finish line D-D first? Justify your answer with calculations. ii) How far behind is the distance of car A from the line D-D when car B reach the finish line? iii) Find the relative velocity of car A to car B at the end of the race.
