# A uniform solid disk of mass \(2.0\text{ kg}\) and radius \(0.50\text{ m}\) is mounted on a frictionless, fixed horizontal axle passing through its center. A light cord wrapped around the outer rim of the disk is pulled with a constant tension force of \(6.0\text{ N}\) tangential to the rim. What is the magnitude of the angular acceleration of the disk?

A uniform solid disk of mass \(2.0\text{ kg}\) and radius \(0.50\text{ m}\) is mounted on a frictionless, fixed horizontal axle passing through its center. A light cord wrapped around the outer rim of the disk is pulled with a constant tension force of \(6.0\text{ N}\) tangential to the rim. What is the magnitude of the angular acceleration of the disk?

![A circular disk is shown in a side-on planar view with a solid dot marking its central pivot. A horizontal dashed line segment extends radially from the center dot to the right edge of the disk, labeled \(R\). The disk is labeled with mass \(M\). A cord is wrapped around the outer circumference and hangs straight downward from the rightmost edge. At the lower tip of the vertical cord, an arrow points downward and is labeled \(F\). A curved arrow indicates clockwise angular acceleration. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787460203-itpCrD.jpg)
