A uniform disk with mass 41.1 kg and radius 0.250 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 26.5 N is applied tangent to the rim of the disk.
What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk has turned through 0.400 revolution? Express your answer with the appropriate units. A 3) ?
