Homework Statement
We have two vectors: one with a speed of 3 m/s to the northwest, let's call this vector a, and we also have a vector b moving to the west with a speed of 5 m/s.
Determine: a + b, a - b and a - 2b
Homework Equations
I have no idea.
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!
