A disk of diameter 80.0cm and mass 50.0g is free to rotate about its center and initially at rest. A lab mouse of mass 30.0g is carefully placed on the edge of the disk at rest. The mouse starts running around at the edge of the disk at a speed of 20.0cm/s relative to the ground. 1) How fast, in rpm, is the disk rotating now? 2) What is the total kinetic energy of the system?

An 80 kg person is standing on the edge of a 50 kg disk whose radius is 1.5 m that can rotate about a pivot in its center. The person starts walking clockwise around the disk and the disk acquires an angular velocity of 3.0 rad/s. Q1) What is the speed (m/s) at which the person is walking on the disk? Q2) What is the magnitude of the person’s angular velocity (rad/s) relative to the ground? Q3) what is the...

The figure shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R2 is 1.0 m, its inner radius R1 is R2/2, its mass M is 7.9 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 7.3 rad/s with a cat of mass m = M/4 on its outer edge, at radius R2. By how much does the cat increase...
