Question

Consider two vectors where F1 = 45 N, F2 = 63 N, and \theta _{1} = 240o and \theta _{2} = 25o, measured from the positive x-axis with counter-clockwise being positive. What is the magnitude of the equilibriant? [to 3 decimal places]

Answer 1

I explained how to do this already, a couple of hours ago. I assumed you know how to add vectors. If you don't, review your course work, or search the internet for a tutorial on vector addition by adding components. You need to make an effort.
