A red ball is heading due east, a blue ball is moving due west, and a green ball is moving north. They have initial speeds vr,i=20 cm/s, vb,i=10 cm/s, vg,i=10 cm/s. The red ball has a mass of 5 g, the blue ball has a mass of 10g, and the green ball has a mass of 5g. The three balls all collide, and stick together. Find the magnitude and direction of the final momentum of the composite.

2. Relevant equations

the sum of P_{I}=the sum of P_{F}

3. The attempt at a solution

Ok...without plugging the numbers in this is what I have so far:

I don't really know how to approach this problem, so if someone could tell me if I am starting it on the right path would be great.

I broke it up into x and y components, and for the x component of momentum I have:

M_{B}V_{B}-M_{R}V_{R}=(M_{R}+M_{B}+M_{G})V_{FX})

Then for the y component I have:

M_{G}V_{G}=(M_{R}+M_{B}+M_{G})V_{FY})

Am I on the right track...or completely missing the point?
