A uniform disk with mass 40.0 kg

By Allen Kazadi

A uniform disk with mass 40.0 kg and radius 0.200 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 퐹=30.0푁is applied tangent to the rim of the disk.a) What is the magnitude 푣of the tangential velocity of a point on the rim of the disk after the disk has turned through 0.200 revolution?b) What is the magnitude 푎of the resultant acceleration of that point in part a?


The magnitude of the tangential velocity is v= 0.868 m/s

The magnitude of the resultant acceleration at that point is a = 4.057 m/s^2
