A uniform disk with mass 8.5 kg and radius 8 m is pivoted at itscenter about a horizontal, frictionless axle that is stationary.The disk is initially at rest, and then a constant force 31.5N isapplied to the rim of the disk. The force direction makes an angleof 35 degrees with the tangent to the rim. What is the magnitude vof the tangential velocity of a point on the rim of the disk afterthe disk has turned through 8.1 revolutions? The unit of thetangential velocity is m/s.
