1. The problem statement, all variables and given/known data
3. Draw figures showing how you would combine a 6 N force and an 8 N force to obtain a resultant force with magnitude (a) 14 N; (b) 2 N; (c) 10 N. 2. Relevant equations 3. The attempt at a solution I just don't know where to start or what equation to use.

Do you understand how to calculate a vector sum graphically? That's all this question is really about...

Combining forces.
Oh wait, like draw a straight line with 8 and 6 for 14, while drawing lines with arrows towards each other for 2?
14 >> 2 ><

I don't really know how to add vectors that well, but wouldnt there be a 90 degree angle between 6 and 8 to give me 10, since 8^2+6^2 square root= 10. Thanks.

I definitely understand what I'm suppose to do much better.
