Given,
From the graph, the total displacement of the given object is d=0-7=-7 m
The total time duration, t=12 s
The average velocity is defined as the ratio of the total displacement to the total time duration.
Thus the average velocity of the given object is,
[tex]\bar{v}=\frac{d}{t}[/tex]
On substituting the known values,
[tex]\begin{gathered} \bar{v}=-\frac{7}{12} \\ 0.583\text{ m/s} \end{gathered}[/tex]
Thus the average velocity of the given object from t=0 s to t=12 s is 0.583 m/s.
