Block A of mass \(m_A\) rests on a horizontal, frictionless tabletop. It is connected by a light string that passes over a pulley to Block B of mass \(m_B\), which hangs freely over the edge of the table. The pulley is a solid uniform disk of mass \(M\) and radius \(R\), and it rotates on a frictionless axle. The rotational inertia of a solid disk is \(I = \dfrac{1}{2}MR^2\). The string does not slip on the pulley. The system is released from rest.
