A uniform disk with mass 395kg and radius 0250 m is pivoted, Ask an Expert

Academics

A uniform disk with mass 39.5kg 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 of 34.5N 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 had turned through 0.150 revolution?

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 0.150 revolution.
