a bomb explodes into three pieces of equal mass. two pieces move off at 120 m/s at right angles to each other. how fast is the third mass moving?

2. Relevant equations

p = mv

pi = pf

3. The attempt at a solution

I know how to do most of these questions, it's just that the wording of this particularly one stumps me. How do I know which direction the third mass travels in?

That's what confuses me about this question. Thanks for any clarity that can be offered!
