What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk has turned through 0 400 revolution? Express your answer with the appropriate units. A uniform disk with mass 40.4 kg and radius 0.300 m is pivoted at its center about a horizontal, frictionless axle that is stationary. The HA 10 E ? disk is initially at rest, and then a constant force 31.0 N is applied tangent to the rim of the disk.
