ANSWER
[tex]9m\/s^2[/tex]EXPLANATION
To find the centripetal acceleration, we have to apply the formula for centripetal acceleration:
[tex]a=\frac{v^2}{r}[/tex]where v = velocity of the vehicle
r = radius of the circular path
Therefore, the centripetal acceleration is:
[tex]\begin{gathered} a=\frac{15^2}{25} \\ a=9m\/s^2 \end{gathered}[/tex]That is the answer.
