9. All lucky guesses

I think questioner want us to assume that the spring is relaxed otherwise there wouldn't be any spring at all. Yup, thanks AlephNumbers :)

Okay, I have to do it with energy conservation. If block is released when spring is relaxed, if it moves x downwards, Work done by grav = Potential energy of Spring. 1/2kx^2 = Mgx kx = 2Mg Then tension is kx everywhere in string. Then equating to (friction + mgsin37) gives answer (A). Is...

I can't figure out how the answer is (A). The spring is the problem. I thought the spring would just extend and whole thing would act like a string. If there were no spring then the answer come out to be (6/5)m. Please help.
