k so question is one you have all answered previously, 3 different forces acting on a single mass, in north south and east directions.

Question

my particular forces are 11.3 N north, 20.4 N east, and 14.7 N south
so to figure out the direction of acceleration in degrees, you have to take the arctan of resultant S, over E.
so that would be arctan 3.4/20.4
though for some reason is not correct, am i doing everything right?

sorry for repeating I just want it to be noticed is all
