A disk (radius, r = 5 m, mass, m = 50 kg) is resting on a perfectly frictionless surface. Two students, Morrigan and Samael, are standing at the outer edge, opposite from each other. Both Morrigan and Samael have masses, mh, = 50 kg (they are both at r = 5 m). At exactly the same time, both Morrigan and Samael start walking counter-clockwise at v = 1 m/s relative to the disk. What is the angular speed of the disk?
