Question

As part of a lab we were asked to find values, graph them and then determine total force and angle of the total force according to the graph. The graph is quadrilateral with the first side being (89 degrees, 2.678 N), the next is (180 degrees, 1.980 N), the third is (271 degrees, 1.185 N), and the last (327 degrees, 2.476 N).

Is there an equation im suposed to be using? and the last line overlaps the first, so do I measure the angle created by the first and last line to find the angle of the total force?

Explanation / Answer

there no equation for this... you just have to add these vectors using vector addition in the graph..by forming parallelograms accordingly.

overlap means you just extend one vector line (in graph) in the suitable direction by the by the magnitude of the other vector.
