A uniform disk with mass $37\mathrm{.}3kg$ and radius $0\mathrm{.}220m$ is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force $33\mathrm{.}5N$ 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 has turned through $0\mathrm{.}130$ revolution?

Express your answer with the appropriate units.

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 $0\mathrm{.}130$ revolution?

Express your answer with the appropriate units.
