Estimate what is the mass of the second disk

Reference no: EM13564165

A solid disk of radius R and mass 2.66 kg is spinning atangular velocity 64.7 rpm about a vertical axis. A solid disk ofradius 2R drops concentrically on the first, so that eventually thetwo cease to slip relative to each other and end up spinning at15.1 rpm. What is the mass of the second disk?
