The figure shows the displacement-time graph of a particle moving on the x-axis. Then,
| 1. | the particle is continuously going in a positive x-direction. |
| 2. | the particle is at rest. |
| 3. | the velocity increases up to a time \(t_0\), and then becomes constant. |
| 4. | the particle moves at a constant velocity up to a time \(t_0\), and then stops. |
The figure shows the position of a particle moving on the \(\mathrm{x}\)-axis as a function of time.
| (a) | The particle has come to rest \(6\) times. |
| (b) | The maximum speed is at \(t=6~\mathrm{s}.\) |
| (c) | The velocity remains positive for \(t=0\) to \(t=6~\mathrm{s}.\) |
| (d) | The average velocity for the total period shown is negative. |
Choose the correct option:
| 1. | (a) and (b) |
| 2. | (b) and (c) |
| 3. | (c) and (d) |
| 4. | (a) and (d) |
