1The figure below shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R2 is 0.770 m, its inner radius R1 is R2/2.00, its mass M is 8.70 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 7.80 rad/s with a cat of mass m = M/4.00 on its outer edge, at radius R2. By how much does the cat increase the kinetic energy of the cat–ring system if the cat crawls to the inner edge, at radius R1?

A 97.3-kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.53 rad/s. A monkey drops a 8.69-kg bunch of bananas vertically onto the platform. They hit the platform at 4/5 of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 21.9 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the...

A playground carousel is free to rotate about its center on frictionless bearings, and air resistance is negligible. The carousel itself (without riders) has a moment of inertia of 125 kg · m2. When one person is standing on the carousel at a distance of 1.5 m from the center, the carousel has an angular velocity of 0.6 rad/s. However, as this person moves inward to a point located 0.918 m from the center, the angular velocity increases to 0.8...

A uniform disk of radius 0.529 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 0.223 N applied at the rim causes an angular acceleration of 0.103 rad/s2. Find the mass of the disk.
