Part A A uniform disk with mass 44.5 kg and radius 0.240 m is pivoted at its center about a horizontal, trictionless axle that is stationary. The disk is initially at rest, and then a constant force 32.5 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 0.250 revolution? Express your answer with the appropriate units. O D) ?
