The figure shows an overhead view of a ring that can rotate about its center like a merry go round Its outer radius R is 1 0 m its inner radius R is R 2 its mass M is 8 0 kg and the mass of the crossbars at its center is negligible It initially rotates at an angular speed of 8 7 rad s with a cat of mass m M 4 on its outer edge at radius R 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 R Number i Units
