angular momentum of a two-particle system(adsbygoogle = window.adsbygoogle || []).push({});

um heres where i get but idk what to do from here some stuff must be perpendicular always and stuff a lil help would be awesome

[tex]

\Sigma_i L_i = \Sigma_i \vec{r_i} \times m_i \vec{v_i} = \Sigma_i (\vec{r_i}+\vec{r_{cm}}) \times m_i (\vec{v_i}+\vec{v_{cm}})[/tex]

[tex]

\Sigma_i ((\vec{r_i} \times m_i \vec{v_i}) + (\vec{r_i} \times m_i \vec{v_{cm}}) + (\vec{r_{cm}} \times m_i \vec{v_i}) + (\vec{r_{cm}} \times m_i \vec{v_{cm}}))[/tex]
