13. Rotational Inertia & Energy / Torque with Kinematic Equations / Problem 22
A solid uniform disk with a mass of 350 g and diameter of approximately 5.00 cm rotates around an axis passing through its center but at one point on its circumference, there's metal scraping against it causing frictional force worth approximately 0.025 N at that particular point. How much time will be required for the rotational speed to decrease by 25.0 rad/s?
