Hey every1! No 1 has been posting so I thought I'd get us going again. .
Today in class Ms. K. went over the answers for the "Advanced Forces" assignment sheet she gave us the other day, on the Smart board. (Check out the link on the last post.) This was after we went over the answers for the "Using Concepts" on the boards in class.
The answers for those were:
1. m = 250 kg
2. F = 3000 N
3. m = 5 kg
4. coeffiecient of sliding friction = 0.255 (no units for this 1 !remember!)
5. acceleration = -2 m/s^2
skip 6
7. a = 3.267 N/kg
other side:
1a) acceleration = 4.9m/s^2
2. max acceleration = 0.2 m/s^2
3. coefficient of sliding friction = 0.4
Then Ms. K. gave gave us another assignment sheet to do. err.. & i think that was all =S
Hope I'm not missing anything! STUDY HARD! + good luck 2morrow!!!
oh ya.. and the next scribe is H2O .. try 2 post this time!
