Inellastic momentum collision w/ angle??

I need help on this one problem.

A .02kg ball of clay traveling east at 2 m/s collides with a .03kg ball of clay traveling 30 degrees south of west at 1 m/s. What is the speed of the resulting 5.05 kg blob of clay?

I really don't understand what to do with the angle.
