You are driving down the road at a constant speed. another car going a bit faster catches up with you and passes you. draw a position graph for both vehicles on the same set of axes and note the point on the graph where the other vehicles passes you. if you have been passed by other car, does it mean that the acceleration of other car is greater than your car at that point in time.
no graphs here.
The other car's speed is faster, but there's no way to tell about its acceleration. It may in fact be slowing down, but still going fast enough to pass you.
