Problem 3: A merry-go-round can be considered a uniform disk of mass 145 kg and radius 2.10 m free to rotate about a frictionless axis through its center. A 40.0 kg child stands at the edge and the system is initially rotating at 0.300 rad/sec. The child begins to walk around the edge of the merry-go-round with a velocity of 0.250 m/s relative to the ground in the direction of the rotation. What is the angular velocity of the merry-go-round...

Figure 11-51 shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R2 is 0.8 m, its inner radius R1 is R2/2,its mass M is 8.8 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 6.5 rad/s with a cat of mass m = M/4on its outer edge, at radius R2. By how much does the cat increase the kinetic...

A uniform disk of radius 0.551 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 0.229 N applied at the rim causes an angular acceleration of 0.103 rad/s2. Find the mass of the disk.
