When the man returns to 0 meters on the position-time graph, the line representing his movement will intersect or touch the x-axis (time axis). This indicates that the man has completed his journey and returned to the starting point.
The reason why the line intersects or touches the x-axis is because at the starting point, the position of the man is 0 meters. This means that the man is not positioned ahead or behind the starting point; he has reached the original position. Therefore, on the position-time graph, the blue line representing his position will align with the x-axis at that specific time when he returns to 0 meters.
What happened to the line on the Position-Time Graph (Blue Graph) when the man returned to the 0 meters? Explain why
