A horizontal disk with a radius of 7 m rotates about a vertical axis through its center. The disk starts from rest and has a constant angular acceleration of 1.7 rad/s 2 . At what time will the radial and tangential components of the linear acceleration of a point on the rim of the disk be equal in magnitude? Answer in units of s.
