A uniform disk with mass 38.0 kg and radius
0.230 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 35.0 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 0.290 revolution?
Express your answer with the appropriate units.
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
0.290 revolution?
Express your answer with the appropriate units.
