Solution: A uniform disk with mass 40 kg and radius 0.20 m is provided at its center about a horizontal frictionless axle. The disk is initially at rest and then a constant force of F = 30 N is applied tangent to the rim of the disk. What is the magnitude of the resultant linear acceleration, a, of a point on the rim of the disk after the disk has turned through 0.20 revolutions?

A uniform disk with mass 40 kg and radius 0.20 m is provided at its center about a horizontal frictionless axle. The disk is initially at rest and then a constant force of *F* = 30 N is applied tangent to the rim of the disk. What is the magnitude of the resultant linear acceleration, a, of a point on the rim of the disk after the disk has turned through 0.20 revolutions?
