A force F = (11.5i + 9.62j + 13.2k)kN acts on a small object of mass 109g. If the displacement of the object is d = (5.63i + 3.81j) m, calculate the work done by the force.(adsbygoogle = window.adsbygoogle || []).push({});

I know W=F*d*cos theta so W=101.4 cos theta

How do I find theta? Do I use the inverse tangant of the F and the d?
