A uniform disk (M = 6kg, R = 1m, I = MR^2/2) can rotate w/o friction about a horizontal axle through its center and perpendicular to its plane. The disk is initially at rest, and a 2kg mass is attached to the rim of the disk directly above the axle. The system is gently put into rotational motion and the disk starts to accelerate. Find the angular speed of the disk when the 2kg mass is at its lowest point. A) 2.7rad/sB) 4.0C) 1.1D) 3.3E) 5.4      |
