To analyze the scenario based on the given information, let's break down the options considering the average speed and the nature of motion.
1. **The ball never went faster than 3 m/s.**
- This statement is not necessarily true. The average speed of a ball can be 3 m/s, but this does not mean it cannot exceed this speed at certain points during its motion.
2. **At a certain point, the ball traveled faster than 3 m/s.**
- This statement could be true. Since average speed can include instances of higher speed and slower speed, it’s plausible that the ball could have momentarily exceeded 3 m/s at some point along the ramp.
3. **The ball traveled at a constant speed of 3 m/s.**
- This statement is false. If the ball had a constant speed of 3 m/s, then the average speed would also be 3 m/s, but there is no indication that the speed does not change throughout the ramp.
4. **It took the ball 3 s to reach the halfway point down the ramp.**
- This statement is also not necessarily true. The average speed of 3 m/s implies that it would take 1 second to travel 3 meters (not necessarily divided evenly). The halfway point would be at 1.5 m, and at an average speed of 3 m/s, it would take 0.5 seconds, not 3 seconds.
Based on this analysis, the most likely statement that could be true is:
**At a certain point, the ball traveled faster than 3 m/s.**
