Question: A uniform disk with radius R = 0.400 and mass 30.0 kg rotates in a horizontal plane on a frictionless vertical axle that passes through

A uniform disk with radius R = 0.400 and mass 30.0 kg rotates in a horizontal plane on a frictionless vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to θ(t) = (1.10 rad/s)t + (8.60 rad/s²)t². What is the resultant linear acceleration of a point on the rim of the disk at the instant when the disk has turned through 0.100 rev?
