A horizontal disk with a radius of 10 cm rotates about a vertical axis through its center. The disk starts from rest at t = 0 and has a constant angular acceleration of 2.1 rad/s². What is the angular speed, of a point at the rim of the disk at the moment when radial and tangential components of the linear acceleration are equal in magnitude? Select one: Oa. 1.00 1/s O b. 0.48 s O c. 1.45 1/s O d. 0.69 s Oe. 1.63 1/s
