If I will consider an axis passing through the center of mass, should I take into account only the momentum derived from rotation: Iω? I assumed the velocity of m and M will be the same. If not, how should I calculate the velocity of m? I have tried to use the conservation of energy, but I don't...

mgR = d(mvR + MvR + ½M(R^2)v/R)/dt mgR = ma + Ma + ½Ma mg = a(m + 3/2M) v = mgt / (m+3/2M) My answer is incorrect. The right answer is v = mgt/(3m+M), but I have no idea what I'm doing wrong.

Hello everyone :) I'm a chemical technologist specializing in galvanic processes, especially in chemical conversion coatings. I'm interested in physics and I hope to find here some help to better understand and solve some physics issues.
