The correct response is: The nine ball traveled a distance of 7 meters and was displaced by 1 meter.
Here's the breakdown:
- Distance is the total path traveled, which is 7 meters for the nine ball.
- Displacement is the straight line distance from the initial position to the final position in a specific direction. Since the nine ball ended up 1 meter to the left of where it started, its displacement is 1 meter to the left.
