Question

Find the average velocity from t = 0 - 12 seconds.-0.917 m/s-1.25 m/s-1.33 m/s-0.583 m/s

Answer 1

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,

$\bar{v}=\frac{d}{t}$

On substituting the known values,

$\begin{gathered} \bar{v}=-\frac{7}{12} \\ 0.583\text{ m/s} \end{gathered}$

Thus the average velocity of the given object from t=0 s to t=12 s is 0.583 m/s.
