Transcribed Image Text:

Two uniform cylindrical disks of identical mass M, radius R, and moment inertia 1/2MR² collide on a frictionless, horizontal surface. Disk I, having an initial counterclockwise angular velocity wo and a center-of-mass velocity Vo = 1/20 R to the right, makes a grazing collision with disk II initially at rest. If after the collision the two disks stick together, the magnitude of the total angular momentum about the point P is A. Zero B. 1/2MR² wo C. 1/2MR²vo D. MRVo E.
