A uniform disk of radius 0495 m and unknown mass is, Ask an Expert

Academics

A uniform disk of radius 0.495 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with same mass as the disk\'s is attached around the disk\'s rim. A tangential force of 0.241 N applied at the rim causes an angular acceleration of 0.103 rad/s2. Find the mass of the disk.
