A disk of mass m, - 60.0 g and radius r, - 4.50 cm slides on a frictionless sheet of ice with velocity v, where v - 13.00 m/s, as shown in a top-down view in figure (a) below. The edge of this disk just grazes the edge of a second disk in a glancing blow. The second disk has a mass m, - 140 g, a radius r, -6.00 cm, and is initially at rest. As the disks make contact, they stick together due to highly adhesive glue on the edge of each, and then rotate after the collision as shown in figure (b). (a) What is the magnitude of the angular momentum (in kg m/s) of the two-disk system relative to its center of mass? kg m2/s (b) What is the angular speed (in rad/s) about the center of mass? rad/s
