Adisk, initially rotating at 120 rpm, is slowed down with a constant acceleration of magnitude 4 rad s2. if the disk has diameter of 20 cm. determine the time does the disk take to stop i. ii the angle does the disk rotate during that time iii. the total angular distance rotated by a disk

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
