Homework Help: Physics

Posted by mathlife on Wednesday, November 3, 2010 at 12:43pm.

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?

No one has answered this question yet.
