Question
Transcribed Image Text:The text reads: "The angular velocity vs. time for a fan on a hovercraft is shown below. Find the angle through which the fan blades rotate in the first 8 seconds."
**Graph Explanation:**
- **Title**: Angular Velocity vs. Time
- **Axes**:
- The horizontal axis represents Time in seconds (s), ranging from 0 to 8 seconds.
- The vertical axis represents Angular Velocity in revolutions per minute (rev/min), ranging from 0 to 400 rev/min.
- **Line Graph**:
- The graph is a straight line with a positive slope, starting at the origin (0,0) and ending at the point (8, 400).
- This indicates that angular velocity increases linearly with time.
To find the angle through which the fan blades rotate in the first 8 seconds, you can calculate the area under the graph, which represents the total revolutions.
