Thank you, I got it. I plotted it and then took the inverse tan to get the angle.

Yeah sure. So far I dotted the two vectors and I got Fnet = 3i - 4j, then F=5 for the magnitude. I then plotted the vectors on a graph and not sure what to do from here.

In the back of my book it gives answers, and the answer for this involves a degree though.

Homework Statement [/B] A block of mass 2kg is accelerated by the two forces F1 = 8i + 3j and F2 = -5i - 7j, (a) What is the net force on the block in unit vector notation, and what is its magnitude and direction? (b) What is the magnitude and direction of the acceleration?Homework Equations...

Oh jeez. Got it now, thank you. Gotta make sure I actually pay attention to units :(
