Homework Statement A disk of mass 6 kg and outer radius 60 cm with a radial mass distribution (which may not be uniform) so that its moment of inertia is \large_{{\frac{2}_{7}}mR^2}. The disk is rotating at angular speed 7 rad/s around its axis when it touches the surface, as shown. The disk...

Homework Statement Consider a 4 kg square which has its mass concentrated along its perimeter, with each side of length 6 m. (a) What is the moment of inertia of the square about an axis perpendicular to the plane of the square at its center of mass? Use the parallel axis theorem and divide...
