Adam,
Although I would have preferred that you solve these problems on your own (and congrats to the physics majors out there who divined the answers), you should note the following:
In both answers, the second part is really independent of the first. Example: plug a different weight into the second problem and Mu is exactly the same. the block could have a mass of a billion kilos with exactly the same answer, Mu = 0.671! In the same way, the answer to problem 1b is dependent only on the acceleration due to gravity.
What you highlighted as a point of frustration is one of the beauties of the universe... Cool eh?
