You are driving down the road at a constant speed. Another car going 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 vehicle passes you

Plzzz Help
just thinking about one car on it's own, if you drew a position vs time graph for a car moving at constant speed, what would that look like ?
but the problem is, if the other car has constant speed...how am i gonna show the point where they meet?
one thing at a time man ! what does the graph look like for one car at constant speed ?
|dw:1411238746219:dw|
linear graph
ok, a straight line, right
yes
now in your question, it says that the other car catches up with you, so that means obviously, that it was behind you to start with, right ?
so you need a graph more like this to start with|dw:1411238919542:dw|
now if the other car started out behind you, but is going faster, you should be able to add the second line to my graph for the other car
there's no rule that says the lines always have to start out from the origin
ic
thats what i thought but i wasnt sure about my answer..and the other concern was, the other car might have acceleration cuz it doesnt say the other car has constant sped
just assume the other car is going at a constant speed but a bit faster than you
