Tues-Day 2
Chem 5 - did qualitative analysis lab in which we identified four unknown salt solutions from a list of possibilities.
7/8 - finish silver oxidation solution stoich problem; start with questions, tomorrow. Finish unit tomorrow.
APB - reviewed quiz errors: Newton's third law; constant v moving object means that a= 0 m/s^2 if no direction change!
Did rope support problem; elevator derivation review and sensibility; rope in elevator question.
Then discussed friction: sliding/skidding and static.
Tomorrow: friction lab/ complex atwood/ ropes/ elevator.
