Question Solved1 AnswerCars A and B are racing each other along the same straight road in the following manner: Car A has a head start and is a distance DA beyond the starting line at t=0. The starting line is at x=0. Car A travels at a constant speed vA. Car B starts at the starting line but has a better engine than Car A, and thus Car B travels at a constant speed vB, which is greater than vA.How long after Car B started the race will Car B catch up with Car A?ive figured xA=x0+vAt and xB=vBtwhat do i do next, setting them equal to each other does not work, right?
