A flat disc on the top of a rough, horizontal table with coefficient of friction \(\mu\) is being rotated with angular velocity \(\omega_{o}.\)

How long will the disc rotate (in seconds) before coming to rest?

First, generalize, and then plug in the following values for the answer: \[\omega_{o}=10 \text{ radian/s},\ \ R=4\text{ m},\ \ \mu =0.3,\ \ g=10\text{ m/s}^2,\ \ M=4\text{ kg}.\]
