Okay here is the problem.
A metal disk ( mass 250g , radius12 cm) is free to rotate about frictionless vertical axle through its center. The axle itself has negligible mass and a radius of 2 cm. A string wrapped around the axle passes over an ideal pulley to a hanging 85 g mass. A dime ( mass 2 g) sits on the edge of a metal disk. The statis coefficient of friction between the dime and the metal disk is u= 0.250.
The 85g mass is released from rest and beginns to fall. How far does it fall before the dime slides of the disk?
I have a hard time to setup the equation.
Any hint or help is appriciated
