A solid cylinder has a moment of inertia 2 kg m2and is rotating freely at a fixed angular velocity of 12 rad/s. Asecond cylinder has a moment of inertia 5 kg m2 andinitially at rest is dropped onto the rotating cylinder.
1. What was the initial angular momentum of the initialcylinder before the dropping?
2. What was the angular velocity of the cylinder pair after the droping?
3. What was the magnitude of the change in the kineticenergy of the system?
