Based on the description of a ball rolling up a ramp, the best statement to describe the motion of the ball is:
**The speed of the ball is decreasing.**
As the ball rolls up the ramp, it is moving against gravity, which causes it to lose kinetic energy and slow down until it eventually stops momentarily before rolling back down.

Based on your description of the graph showing the velocity of the horse increasing linearly over time (from 5 m/s to 10 m/s to 15 m/s), the best statement to describe the horse's motion is:
**The horse maintained a constant acceleration during this portion of the race.**
This is because the increase in velocity over equal intervals of time indicates a constant acceleration.
**The horse maintained a constant acceleration during this portion of the race.**
This is because the increase in velocity over equal intervals of time indicates a constant acceleration.

The statement that is an example of velocity is:
**A car travels east at 55 kilometers per hour.**
Velocity is defined as the speed of an object in a given direction, which is why this statement qualifies as an example of velocity. The other options provide distance or speed without directional components.
