# Disc Rotated Flatly?

A disc is rotated with angular velocity $$\omega_{o}$$ and kept on a floor with its area on the surface of table with coefficient of friction being $$\mu$$ as shown in figure.

Find the time after which it stops( in seconds)?

First Generalize, Then put these values for answer

• $$\omega_{o}=10 rad s^{-1}$$
• $$R=4 m$$
• $$\mu =0.3$$
• $$g=10 m/s^2$$
• $$M=4 kg$$
