In class today - Senior version 1/17,18

Thanks to either software gremlins or hardware ID-ten-T errors, you'll need to get your class information here until further notice.

Today:

1. Review the homework from last time. (my solutions here)
2. A quick homework quiz.
3. A review of Newton's 2nd Law in preparation for the test next class period - Friday 1/19 for G4, Monday 1/22 for M1.

Be ready for some good old-fashioned tough brain work today!
