I got the first part, but I don't know how to get acceleration. How do you find the force of kinetic friction? How did my teacher get to the assumption that mu k = .37?
I already emailed this to you, even though you didn't wait for my reply and went to a physics forum. GRR. For the sake of maintaining my rep:

I'd do the others too, but I don't have time. Good luck.

I edited my above post to make the image show up for the last question. Can you do those 2? I'm guessing they aren't hard, you just need to understand specific concepts to do them. There are those questions that you just make mistakes on then there are those that you don't get because there's an unusual way of approaching them.

Question 4:

Typo: should be "because" and not "by" in the statement.

First one was great, thanks. Clarified how to deal with friction in vector addition (it's the same way as usual). The reason I got my angle and Fa wrong is b/c I messed up the cosine law calculation. I BLAME THIS DAMN CALCULATOR.

Reading the other one now.

WOW. I DIDN'T EVEN THINK OF 9.81. SO DUMBBBBB.
