# Adding Horizontal Vectors Graphically

1. The problem statement, all variables and given/known data
I am asked to add two horizontal vectors graphically. The result being the Cvector:
Cvector= Avector + 2*Bvector

2. Relevant equations
Avector has a length of 4 in the east direction.
Bvector length 1 in the west director.

2*Bvector= length 2

3. The attempt at a solution
Cvector has a length of 6. I know that. But while drawing them graphically, I end up drawing Avector - 2*B vector instead of adding both vectors.

How can I show the addition of both horizontal vectors?

Hi Lemniscate

I don't think vector C has a length of 6. Assume that the positive direction is the east direction, so we have vector A = 4 and vector B = -1. Adding them will end up as subtraction.

Hm. I see what you're saying.
In my problem, the length of vector C is 2.

Thank you, songoku!
