The drawing shows a 28.8-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, F1 and F2, are applied to the crate, and it begins to move. The coefficient of kinetic friction between the crate and the floor is k = 0.374. Determine the (a) magnitude and (b) direction (relative to the x axis) of the acceleration of the crate.

m=28.8kg

k(kinetic friction)=.374

F1=88N

F2=54N

fk(magnitude of kinetic friction)= (k)(Fn)

ax= (-fk)/m

I have tried a few things, but i am not sure really what equation to go after, since i feel i should be using something with the angles in it.

any help is appreciated.
