I'm having a bit of trouble with a Free Body Diagram question and I'm not sure if I'm going about it properly.

The question asks;

A 82kg couch is being pushed with a force of 56N at an angle of 40 degrees above the horizontal. If the coefficient of friction between the couch and the floor is 0.051, what is the acceleration of the couch?

My final answer was it accelerated at 0.02m/s^2.

I think I am incorrect because the acceleration in the vertical has to be 0, and therefore Fg, Fn and Fappv must balance out to 0. If so, I will have a different Fn. Can someone let me know if I'm on to something?
