This is my solution but I couldn’t find $h$ in term of $V \rightarrow M_{1} V - M_{2} V = M_{2} V_{2} \implies V \left( M_{1} - M_{2} \right) = M_{2} V_{2} \implies \frac{M_{1}}{M_{2}} = 1 + \frac{V_{2}}{V}$ and $V = V_{2} - V$ so $V_{2} = 2 V$ $\frac{M_{1}}{M_{2}} = 3$ if we apply Energy conservation $3 g h + \frac{3}{2} V^{2} + g h + \frac{1}{2} V^{2} = \frac{1}{2} 4 V^{2}$ (I think there is a mistake at the end)
