A solid cylindrical disk has a radius of 0.20 m. It is mounted to an axle that is perpendicularto the circular end of the disk at its center. When a 30 N force is applied tangentially to the disk, perpendicular to the radius, the disk acquires an angular acceleration of 150 rad/s2.What is the mass of the disk?
