Answer

Final Answer: $\boxed{\frac{4 \pi}{25}}$ radians per sec.

Steps

Step 1 :The question is asking for the value of $\omega$ in the formula $s=r \omega t$. We know the values of $s$, $r$, and $t$, so we can rearrange the formula to solve for $\omega$ as follows: $\omega = \frac{s}{r \cdot t}$.

Step 2 :Substitute the given values into the formula: $s = \frac{4 \pi}{5}$, $r = 1$, and $t = 5$.

Step 3 :Solve for $\omega$ to get $\omega = \frac{4 \pi}{25}$.

Step 4 :Final Answer: $\boxed{\frac{4 \pi}{25}}$ radians per sec.
