Homework Statement
A massive cylindrical container of inner radius ##R## is rotating freely with an initial angular velocity ##w_0##. A liquid of density ρ is slowly injected into the container, until the container is fully filled except the center of the container. The angular velocity of the whole system reduces to ##w## after the injection. What is the container's moment of inertia, while the gravitational acceleration is ##g##?
Homework Equations
The moment of inertia equation.
