Answer 1

I can’t see the image you referenced. Could you either upload the graph image or briefly describe each graph (are they position vs. time or velocity vs. time, and what each looks like)?

Tip to identify the correct choice:
- If the plots are position vs. time: the car not moving is the graph that is a horizontal (flat) line — position does not change with time.
- If the plots are velocity vs. time: the car not moving is the graph that is a horizontal line at v = 0.

If you tell me which graph is flat (or which is at zero velocity), I’ll point to the correct letter.
