There is a spring of constant which rests on an slope inclined at an angle of to the horizontal. The coefficient of friction of the slope is . A block of mass compresses the spring by a distance , and when the block is released, travels a distance up the slope.
In terms of the other variables and ,
a) Find .
b) Find , the distance the spring will be compressed when the block returns to the spring.

(For those who don't do specialist, )
The only units are , , , .

There are many variations and evil things which could be added to this question (if it's not evil enough), and I might later...  :knuppel2:
