(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

We have two vectors: one with a speed of 3 m/s to the northwest, let's call this vectora, and we also have a vectorbmoving to the west with a speed of 5 m/s.

Determine:a + b,a - banda - 2b

2. Relevant equations

I have no idea.

3. The attempt at a solution

I tried to put the vectors in terms of unit vectors, but that didn't work, then I tried to use Pythagoras' Theorem, but that wasn't right either. I'm getting really frustrated with this problem!
