Mmm?.. =l..

@4thKyuubi I meant, PE at the beginning of the lecture, why was PE = 0?

[4thKyuubi]

Also, why is Uf = to 0?

[4thKyuubi]

And what was the question?

@snowman78619 What does (1/2)k(xi^2) mean?

[4thKyuubi]

PE is Potential energy which was U in the previous lelture?

@lhlatimer look at his handouts on the website! (if you still need to lol)

I'm confused. Why is your table of contents so simple now? What about topics?? :S:S

We seem to be coming into this problem solving without discussing the equations being used,  There is no prelude.
