I'm sorry that this is probably a repeat topic, but I am having a hard time using other threads as examples. This is probably really easy, I just can't seem to figure it out the way our teacher taught it. I'll try and make this short and simple. 1. The problem statement, all variables and given/known data There are three forces acting on a single point. One is 15 N north; the second is 15 N west; and the final is 15 N at 30 degrees east of north. Determine the magnitude and direction of the resultant force. 2. Relevant equations Basic trig (sin, cos, tan), a^2 + b^2 = c^2. This is all we have been taught in this class and are expected (and should be able to) solve with just this. 3. The attempt at a solution PHP: 10 N north | / | / 15 N 30 degrees east of north <-----------|/ 15 N west From there I am unsure of what I could do to easily solve it (also a little unsure of what I am even solving for).
