A uniform disk with mass 36.3 kg and radius 0.300 m is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force 25.5 N is applied tangent to the rim of the disk.

Answer:
Part A
What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk has turned through 0.220 revolution?
