Finding acceleration of snow boarder

[alaa amed]

Consider a snow boarder going up a 5.5° slope. Assume the coefficient of friction for waxed wood on wet snow is μk=0.10 and he is moving in the positive direction.
Calculate the magnitude of the acceleration of the snow boarder in m/s2.

All right. So the procedure is to first draw a diagram showing all the forces on the body, then specifying a coordinate system, which specifies what you mean by "moving in the positive direction." The diagram is called a free body diagram. Once you draw the diagram, we can take the next steps easily.

This is the FBD, but I do not think it's correct.
