1. The question I'm struggling on has been answered on here before but with different values. Here is the link to the question https://www.physicsforums.com/showthread.php?t=344213 but on mine I have a 1.9kg object and F1=5 and F2=2. I figured out that the Y components are 0 for both of them and I have the x component solved for F1, but I was sort of following it step by step and I'm unsure of why I did what I did. The equation used by gbednba in this example was Ax=3sin20=1.02 --> -1.02-1+5=2.97/2.6=1.14 which is the answer. I don't really understand what the 20 degree angle has to do with solving it, so if you could help me incorporate it into the problem I would appreciate that a lot. I guess I just don't really know what is going on here so if you can help me out, that would be great. Oh and the one problem I still have to solve is for Ax of diagram B, which I don't even know what to do for.
