    Angular Momentum of a candy dish

    Homework Statement A candy dish that rotates is called a lazy susan. This lazy susan is a uniform disk (mass 0.876 kg, radius 0.244 m), rotating about the center of the disk on a frictionless bearing. Suppose a large bug of mass 35.9 g sits at rest at on the edge of the empty lazy susan, which...
