I don't undertsand these questions
![**Graph Description:**
The graph represents velocity \(v(t)\) in meters per second (m/s) against time \(t\) in seconds (s). The velocity-time graph is divided into distinct segments:
1. From \(t = 0\) to \(t = 4\) seconds, the velocity increases linearly from 10 m/s to 30 m/s.
2. From \(t = 4\) to \(t = 7\) seconds, the velocity remains constant at 30 m/s.
3. From \(t = 7\) to \(t = 8\) seconds, the velocity decreases linearly from 30 m/s to 0 m/s.
4. From \(t = 8\) to \(t = 9\) seconds, the velocity remains constant at 0 m/s.
