A stationary disk rotates to angular speed of 600 rpm in 12 3. Assuming the angular acceleration is uniform, compute the (a) angular acceleration: of the disk in rad/53. (b) angular displacement of the disk. (c) tangential speed of an ant riding on the rim of the disk if the radius of the disk is 5 cm. ((1) tangential acceleration of an ant riding on the rim of the disk of the radius of the disk is 5 cm. (e) torque acting on the disk if the mass of the disk is 250 g and radius 5 cm. [Given 1com for disk = g MR2]
