The radioactive core decayed into three fragments of mass $m_1$, $m_2$, and $m_3$, having mutually perpendicular velocities $v_1$, $v_2$, and $v_3$, respectively. What was the speed of the nucleus before the decay?
Since velocity's vectors are mutually perpendicular, their directions can be fundamental for establishing the spatial coordinated system. So, let be $\hat{v_1}$, $\hat{v_2}$ and $\hat{v_3}$ the unitary vectors for each direction. Applying MCL for each direction,
$$(m_1+m_2+m_3)V_1 = m_1v_1 \;(1)$$
$$(m_1+m_2+m_3)V_2 = m_2v_2 \;(2)$$
$$(m_1+m_2+m_3)V_3 = m_3v_3 \;(3)$$
where $V_1$, $V_2$ and $V_3$ are the components of velocity $\vec{V}$,
