A uniform disk that has a mass M rotates freely about a horizontal axis that goes during the center and is perpendicular to the plane of the disk. A particle of mass m rests at the top of the disk on the rim directly above the pivot. As the particle reaches its lowest point what is the (a) angular speed of the disk and (b) the force exerted by the disk on the particle
