I think that your problem can be represented by this drawing: |dw:1444056374728:dw| here we can write the subsequent equations: $\left\{ \begin{gathered} - {m_A}g + \tau = {m_A}a \hfill \\ - {m_B}g + \tau = - {m_B}a \hfill \\ \end{gathered} \right.$

where $$a$$ is the acceleration of the system, and $$\tau$$ is the mechanical tension of the cable. Please solve that system for $$a$$

@Michele_Laino Sir Thanks :)
