Respuesta :

ANSWER:

3.08 m/s²

STEP-BY-STEP EXPLANATION:

Given:

Initial speed (u) = 2.5 m/s

Final speed (v) = 25 m/s

Time (t) = 6.5 s

We can determine the acceleration by the following formula:

[tex]\begin{gathered} v=u+at \\ \\ \text{ We replacing:} \\ \\ 25=5+a\cdot6.5 \\ \\ 6.5a=25-5 \\ \\ a=\frac{20}{6.5} \\ \\ a=3.08\text{ m/s^^b2} \end{gathered}[/tex]

The acceleration is 3.08 m/s²
