(adsbygoogle = window.adsbygoogle || []).push({}); Antother Collision!!!!!!!!!

A billiard ball moving with a speed of [tex]v = 2.2m/s[/tex] strikes an identical stationary ball a glancing blow. After the collision, one ball is found to be moving at a speed of [tex]v_2 = 1.1m/s[/tex] in a direction making a [tex] \theta = 60^o[/tex] angle with the original line of motion. Find the velocity of the other ball?

I dont really know where to start...Maybe conserving momentum?
