To accurately determine in which sections the bike's kinetic energy is increasing, we would typically need a description or a visual representation (like a graph or a chart) showing the bike's speed, position, or any forces acting on it throughout each section.
In general:
- Kinetic energy increases when the speed of the bike is increasing.
- If the bike is going downhill or accelerating, it will likely be gaining kinetic energy.
- Conversely, if the bike is slowing down or going uphill, the kinetic energy would be decreasing.
If you can provide details or context for each section (such as speeds, inclines, or accelerations), I could help you determine where the kinetic energy is increasing.
