- Homework Statement:
- Find the angular momentum of the system of two particles in the figure connected by a (massless) rigid bar.

- Relevant Equations:
- $$L=r_{left}\times mv_{left}+r_{right}\times mv_{right}$$

Lets do it for the left (the right will be similar): ##r_{left}=[(L-a\sin\theta)\sin\phi,(L+a\cos\theta)\cos\phi]## so ##v_{left}=[-a\dot{\theta}\cos\theta\sin\phi+(L-a\sin\theta)\dot{\phi}\cos\phi,-a\dot{\theta}\sin\theta\cos\phi-(L+a\cos\theta)\dot{\phi}\sin\phi]##. Is this right?
