In the future if you have something negative to say, do so in a private message. Common civility affords me that right, and I shouldn't have to state that so bluntly to another adult. I gave an example of only half of the problem at most. I can understand how the site...
No problem
MKWOK,
No problem. It's good to see how the concept is supposed to work sometimes, so that you can see how to apply it. Apply that concept to the remainder of the problem, and you will be able to get your final answer.
Good luck.
The Setup
This looks like an interesting problem. Some things to remember.
1) it's the frictional force that is doing all of the moving in this case. So the sum of the forces should look something like this:
\sumFx = ma - fk
..
ma = f(force of friction)
ma = \muN
ma = \mu(9.8)(m)...
