1. The problem statement, all variables and given/known data If θ=30 degrees find the direction and magnitude of the resultant of these forces. [PLAIN]http://img194.imageshack.us/img194/7899/image2iw.jpg [Broken] 2. Relevant equations 3. The attempt at a solution Ok, so I know I have to add both of the vectors. I need to find the coordinates to do so. The first vector's coordinates must be <220,0>. Next I need to find the second vector's coordinates: x=150cos30 x=[150√(3)]/2 y=150cos30 y=75 so the second vector has the coordinates <[150√(3)]/2,75> If you add the second and the first vectors you get <[590√(3)]/2,75> Then I found the magnitude of this new vector to be 590.63 newtons. However, this is wrong because the book's answer section says the magnitude should be 357.85 newtons. If i go on to find the direction that also turns out wrong. What am I doing wrong?
