Block 1 of mass \(m_1\) rests on a horizontal, frictionless table. It is attached to a light, inextensible string that passes over a pulley at the edge of the table and is connected to Block 2 of mass \(m_2\), which hangs vertically. The pulley is a uniform solid disk of mass \(M_P\) and radius \(R\) that can rotate freely about its center. The rotational inertia of the pulley is \(I = \dfrac{1}{2}M_P R^2\). The string does not slip on the pulley. The system is initially held at rest.

At time \(t = 0\), the system is released. After Block 2 falls a distance \(D\), the string suddenly breaks.
