Thanks for the great explanation, I got it!

Thanks! That was my problem, my brain was burnt out so I just tried to do it all in one go rather than by components. Didn't work :P

Homework Statement Two forces F1 and F2 are acting on a mass M=4kg. The force F1 = 7i + 6j + 8k, in N. The acceleration of the mass is given by a = 1i + 3j + 2k, in m/s2. Calculate the magnitude of F2 . Homework Equations F=ma The Attempt at a Solution F1+F2=ma m=4kg...
