The picture shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R, is 0.810 m, its inner radius R, is R2/2.00, its mass M is 8.6 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 7.56 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 in Joules of the cat-ring system if the cat crawls to the inner edge, at radius R? R1 R2

A wheel is rotating about a fixed axis with constant angular acceleration 3 rad/s2. At different moments, its angular speed is 2 rad/s, 0. and +2 rad/s. For a point on the rim of the wheel, consider at these moments the magnitude of the tangential component of acceleration and the magnitude of the radial component of acceleration. Rank the following five items from largest to smallest: (a) |at| when = 2 rad/s, (b)|ar| when = 2 rad/s, (c)|ar| when = 0, (d) |at| when = 2 rad/s, and (e) |ar| when = 2 rad/s. If two items are equal, show them as equal in your ranking. If a quantity is equal to zero, show that fact in your ranking.
