Well it's Nicole because Kim had to work today so she will be doing the post for tomorrow, so I will begin.
Today we got our tests back once we all sat down and for most of us it wasn't exactly the greatest. We then went over the answers that I am sure Ms. Kozoriz will be posting later.
We then got some important defenitions, which were:
Dynamics - motion and forces
Statics - all forces are balanced to keep objects still
Static equilibrium - object's state of no motion when all the forces acting on it are balanced
Dynamic equilibrium - not moving or at constant acceleration
We also went over questions 1-3 on p.237 from Friday's class. The answers were:
1. adj= 5000N opp=8660
2. 68.4N
3. a) free body diagram
b) 0.039m
c) 0.45kg
We were then told to do the first page of Ch. 7 Study Guide and finish up questions #1-3 on p. 266 and #18-20 on p.267. So that was every for today and tomorrow it will be KIM!
