Vectors
I am having some trouble doing this vectors question and was hoping for some guidance on how to complete it.
The question is as follows: Using vector components, find the resultant R for the sum of two vectors A and B shown in the diagram.

Seems relatively straightforward.
Can you state the difficulty.
The vertical (y) components of A and B are in the same direction (up) so they add and the resultant is therefore also up.
The horizontal (x) components of A and B are in opposite directions so the larger subtracts the smaller.

Hi Clyner82, In working with vectors is easier (and faster) to use entire vectors than it is fish out one
component then fish out the other. Each vector takes care of its own components.
Here's two other problems.

Good luck, JP
