Question

A uniform disk with mass 41.1 kg and radius 0.290 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 of 28.5 N is applied tangent to the rim of the disk. 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 0.400 revolution? Express your answer with the appropriate units. v = Part 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 0.400 revolution? Express your answer with the appropriate units. a =
