Question

A uniform disk with mass 44.0 kg and radius 0.200 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.

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 0.180 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 0.180 revolution?
