A uniform disk with radius 0.350m and mass 25.5 kg rotates in a horizontal plane on a friction-less vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to theta(t)= (1.30 rad/sec)t + (8.30 rad/s^2)t^2 . 1. What is the resultant linear acceleration of a point on the rim of the disk at the instant when the disk has turned through 0.300 rev? Express your answer with the appropriate units.
