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. Attached Thumbnails

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.

Each vector takes care of its own components. Here's two other problems. http://www.thermospokenhere.com/wp/0...h/pharaoh.html http://www.thermospokenhere.com/wp/0...trig_laws.html http://www.thermospokenhere.com/wp/0...istance_1.html Good luck, JP Attached Thumbnails
