A uniform disk with mass $42\mathrm{.}0$ kgkg and radius $0\mathrm{.}230$ mm is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force $29\mathrm{.}0$ NN is applied tangent to the rim of the disk.

What is the magnitude vv of the tangential velocity of a point on the rim of the disk after the disk has turned through $0\mathrm{.}250$ revolution?

Express your answer with the appropriate units.

What is the magnitude aa of the resultant acceleration of a point on the rim of the disk after the disk has turned through $0\mathrm{.}250$ revolution?
