Mechanics question watch

1. Hey all, I was stuck on a question on this paper: http://mei.org.uk/files/papers/M2_2016_June.pdf
and I feel like I'm missing something obvious. It's question 2.b)i) , and I don't understand why GPE isn't taken into account for an energy calculation of a block moving up a slope, just KE is used. Thanks for your help.
2. Hi, I had an attempt on the question and my answer agrees with the mark scheme (page 10 of the entire PDF document). The mark scheme accounts for the gravitational potential energy.

I have attached a screenshot of the mark scheme with the potential energy marked out in red.

What did you see and what have you done? :-)

Thank you! That makes sense, I just somehow split it into parts and confused myself, with 2 GPEs bizarrely, thanks for your help, knew I was missing something simple.
