The velocity versus time graph of a body moving in a straight line is as shown in the figure below:

1. The distance covered by the body in \(0\) to \(2~\text{s}\) is \(8~\text{m}\).
2. The acceleration of the body in \(0\) to \(2~\text{s}\) is \(4~\text{ms}^{-2}\).
3. The acceleration of the body in \(2\) to \(3~\text{s}\) is \(4~\text{ms}^{-2}\).
4. The distance moved by the body during \(0\) to \(3~\text{s}\) is \(6~\text{m}\).
