A ring (mass M) and disk (mass M) with radii R rotate in opposite directions.The ring rotates Clockwise with an angular speed 3ω, and the disk rotates Counterclockwise with a speed 2ωThe ring and the disk then "collide" and rotate together with the same ωf. What is the initial angular momentum of the ring. Remember, if the angular momentum is pointing down, it is negative, if it is pointing up it is positve.-3 MR2ω
What is the initial angular momentum of the disk? Remember, if the angular momentum is pointing down, it is negative, if it is pointing up it is positve.
What is the total angular momentum of the disk and ring together?
What is the Moment of Inertia of the ring plus disk?
What is the Angular velocity, ω of the ring plus disk after the collision?
As shown below, a bullet of mass m and speed v is fired at an initially stationary sphere. The bullet goes through the sphere, and exits with a speed of. The sphere is attached to a rigid pole of

length L and negligible mass. What is the minimum value of v such that the sphere will barely swing through a complete vertical circle? (Use the following as necessary: m, L, g, and M for the mass of
the sphere.)

Use conservation of energy to determine the speed of the sphere immediately after collision. Assume that at the top of the swing the sphere is momentarily at rest, so its kinetic energy is zero. Then
apply conservation of momentum to find the initial minimum speed of the bullet.

When the ring is rotating at a constant angular velocity o each rope forms a constant angle 0 with the vertical as shown in Figure II. Let the mass of cach rider be m and neglect friction, air resistance, and the mass of the ring, ropes, and seats.
