## Main Question or Discussion Point

I have a question regarding rotation and kinetic friction that I cant find anywhere else on the web.

Say you have a ball of radius r and mass m rotating on a flat surface without any forces acting on it but the force of friction. How does the deceleration of the ball relate to the frictional coefficient of the surface?

Is there a simple equation that describes the force of kinetic friction acting on the ball?
