1. The problem statement, all variables and given/known data Car A travel at uniform velocity at 20 metre per second from t=0s. Car B starts with 5 metre per second during t=0s and accelerates uniformly to 30 metre per second in t=30s.It travels at constant velocity of 30 metre per second from there onwards 2. Relevant equations 3. The attempt at a solution A velocity-time graph is plotted for this question. But i just simply dunno wad to do regarding the maximum distance between both of the cars before Car B catches up with Car A. I need urgent help and i mean it,thanks... what can i do with the graph to solve this question?
