1. The problem statement, all variables and given/known data http://imgur.com/a/FyekZ I took the liberty of uploading everything. The first picture is the question, while the other two is my attempt at answering it in two parts. What I do not understand is what I did wrong or where I went wrong. I also would like to know why, unlike many other questions from the text, this question does not specify in which direction the resultant force is directed. Is the question wrong, or am I supposed to go about this in a different manner?

Relevant equations See above. 3. The attempt at a solution Please see above.
