I have a homework question in which a sticky hockey puck traveling at constant velocity parallel to the side of the rink strikes a stationary puck and sticks to it. The angels between centres at collision is 30 degrees. I must find the angular velocity of the two pucks stuck together.

I first found the center of mass velocity by the principal of conservation of momentum to be $$\frac{v}{2Cos(\alpha)}$$ where alpha is the direction of travel of the two pucks together. I am bogged down after this, partly because I am not sure if it is correct and partly because I am not sure of the most efficient method of calculating the angular velocy. By the way both pucks have mass $p$ and radius $h$. As this is homework, I would like some help in understanding and figuring this out myself rather that a straight solution.

Thanks
