V1=V2=V3 II II II m1 m2 M3

It seems like you are referring to a system of equations or a set of variables where \( V_1 \), \( V_2 \), and \( V_3 \) are equal (i.e., \( V_1 = V_2 = V_3 \)), and you have masses \( m_1 \), \( m_2 \), and \( M_3 \). However, the context of what you are asking for is not clear.

If you're studying physics, this could relate to a problem about conservation of momentum, energy, or another concept involving these variables.

Could you provide more context or clarify what specific question you have regarding this setup? Are you looking to solve for a specific variable, analyze forces, or something else?
