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: 1. The problem statement, all variables and given/known data 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) 2. Relevant equations ?? 3. The attempt at a solution [/PLAIN] [Broken] Thanks in advance!
