Two forces(adsbygoogle = window.adsbygoogle || []).push({});

F1 = -8.20i + 4.30j and

F2 = 7.10i + 4.60j

are acting on a mass of m = 6.90 kg. The forces are measured in Newtons. What is the magnitude of the object's acceleration?

i tried to add the vectors and using the f=ma to find acceleration but the answer is wrong.

please help

thnx
