A uniform disk with radius 0.650 m
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)=(1.10rad/s)t+(6.30rad/s^2)t^2.
Part A
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?
Express your answer with the appropriate units.
