Hey, I'm having problems with this:(adsbygoogle = window.adsbygoogle || []).push({});

A particle m with initial speed V1 collides with a particle at rest with mass 3m. After collision, particle with mass m is seen moving 30 degrees from its initial direction. What is the angle of motion of the 2nd particle after collision?

I can get three equations from momentum and energy for three unknowns but I can't solve it. Help?
