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

I have no idea what angle you are computing. The above is correct for the angle as measured S of E.

sorry, uhm so first I figured out the acceleration of the mass, which was 5.78m/s^2. Then it asks what is the direction of acceleration, if you take east to be zero degrees and counterclockwise to be positive

Lord. I gave you the angle S of E, you want it measured from E counterclockwise all the way around. Is is possible for you to draw the figure? angle=360-arctan( )

Do you need a tutor? This is all very basic stuff.

yeah, and that wasn't the right answer. Its why i was asking you, you tool.
