On a rough floor with coefficient of kinetic frction $\mu_k$, a horizontally placed uniform circular disk of radius $R$ is rotating about a fixed point on it's circumference with angular velocity $\omega_0$.

The time taken by the disk to stop is $t = \dfrac{a}{b} \dfrac{\pi R \omega_{0}}{\mu_{k} g}$, where $a$, and $b$ are positive coprime integers. Find the value of $a+b$.
