I can’t see the graphs you mention. Please upload the image or describe each graph (is it position vs time or velocity vs time, and the shape of each curve).
How to tell which one shows constant speed:
- If the graph is position vs time: constant speed appears as a straight line with constant (nonzero) slope. A horizontal line means the car is stopped (zero speed); a curved line means the speed is changing.
- If the graph is velocity vs time: constant speed appears as a horizontal line at some nonzero value. A sloping line means acceleration (speed changing); a horizontal line at zero means stopped.
If you upload or describe the graphs I’ll pick the correct letter.
