Explanation:
In the initial situation, the ball has kinetic energy due to its motion. When the friction caused by the gravel patch acts on the ball, some of this kinetic energy is converted into other forms, such as heat and sound, causing the ball to slow down. Here's a simplified kinetic energy bar chart to model the situation:
```

This represents the decrease in kinetic energy due to friction.
