I JUST started adding vectors.. as in.. last class. I got a ton of questions, and have done three of them. The answers are given, but I got them wrong. I'll follow the little template already given:

What is the net force on a stack of books which are applied two forces: 2.0 N 61 degrees N of W and 59 degrees N of E?

The answer is 75.0 N, 73 degrees (N of E)
