I Review I Constants
A uniform disk with mass 38.4 kg and radius 0.260
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 29.0 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 0.270 revolution?
Express your answer with the appropriate units.
