A box is sitting ona surface, using the givens shown find the normal force, the frictional force, the applied force, and the force of weight in N.

ax = 2 m/s^2
ay = 5 m/s^2
u = 0.36
m = 55kg
FA2 = 14 N
FA3 = 15 N
Theta = 22 Degrees

I can't interpret that illustration since there are no arrows pointing the direction of the applied forces.

The weight W = mg points downward with gravity.

Fa3 is at theta=22 degs?

Fa2 is parallel with horizontal?
