This is why I said in my opening post that I thought the problem was invalid as written. Not the first time with this person. I am mostly checking here to see if I am missing something.

The problem says the force is 200N, and variable forces are not part of this course, so the marking on the picture is ignored I guess. Yes this is the amount of care I have come to expect in figure reuse from this instructor.

I put in the image of the problem in the only spot I could figure out how to do so. I am confused as to why people seem to be having trouble with the post itself. As to the problem being confusing, I agree. I mentioned the assumptions I was making in my work section (where the axis are, etc)...

Yes I agree the problem is not well written. I took it to be the block moving down slope, with the 2 m being along the x axis (not the slope), with the 200N pointed downslope, the spring pulling up slope.

That is the homework complete statement. There is no earlier part. I included the picture in the main text. No way I can see to add an image to the problem statement.

Note: wording is ambiguous so I assumed spring started from equilibrium, in which case it stretches as we go downslope. Final height (at lower point on slope) is 0. Distance along slope = Distance the spring stretches = d= ##s_f## = ##2/cos{\theta}## =2.13 Height change = h = ##2 tan{\theta}##...
