conservation of momentum in a perfectly inelastic collision ...

$m_x v_{x0} + m_y v_{y0} = (m_x + m_y) \cdot v_f$

note that velocity is a vector (magnitude & direction)

fyi, this problem should be in the physics section

Also note that \(\displaystyle m_x = m_y = M\), which cancels out so you don't need to know what the mass is.

Thank you :)
