Start with a picture and free-body diagram.

I have a free body which a 140 N force going along the + x axis a N force (normal) going + along Y axis a vector "W" in the third quad with a polar angle of 235'. What do i do next. I know that i need to find the acceleration of the block. Where and how does the coeficient of friction come into play here?

I still need that picture with all forces shown. There is gravity and friction in addition to that 140 N force. The resultant force accelerates the block.
