Today in Physics class....
FIRST
We went over the questions in the duck book (MS. K has posted the answers below).
SECOND
We learned about Hooke's law of elasticity which is "an approximation that states that the amount by which a material body is deformed (the strain) is linearly related to the force causing the deformation (the stress)."
Note the following equations:
Hooke's Law
F=kx
Spring Potential Energy
Es=1/2kx2
Gravitational Potential Energy
Ep=mgh
THIRD
We were given a lab that was related to Hooke's law. There are questions included in this lab and it will be due tomorrow although we are supposed to be getting some time to work on it tomorrow as well.
The equations you see above should come in handy if you're trying out the questions for the lab.
Sorry this isn't the most extensive post, but I've got work soon and I still need to work on my lab.
Tomorrow's Scribe will be....

I think you should check those equations again. Make sure we cover this in class tomorrow. Nice spring!
