A solid sphere \(I = 0.06\,\text{kg}\cdot\text{m}^2\) spins freely around an axis through its center at an angular speed of \(20\,\text{rad/s}\). It is desired to bring the sphere to rest by applying a friction force of magnitude \(2.0\,\text{N}\) to the sphere's outer surface, a distance of \(0.30\,\text{m}\) from the sphere's center. How much time will it take the sphere to come to rest?
