Hi,

I am having trouble recalling my concepts in momentum. I just remember its conserved

Plus, I am horrible with directions, so need help understanding this problem, as well as the underlying concepts.

What I am doing is as follows:

15*m + 15*m = m(15 + 15)

which doesn't take me anywhere

Do I need to resolve into x and y components?

So any help on this question would be greatly appreciated. I will try and return the help by helping others. (i.e. pay it forward!)

*Two pool balls are rolling along a pool table. The orange pool ball has a velocity of 15 cm/s west and the green ball a velocity of 15 cm/s north 30° east. What are the velocities of the balls after the collision?*
