A uniform disk with mass 37.0 kg and radius 0.270 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 28.0 N is applied tangent to the rim of the disk. 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 0.240 revolution? b) What is the magnitude a of the resultant acceleration of a point on the rim of the disk after the disk has turned through 0.240 revolution?
