Brief Lab QUIZ today!

Then, we'll try to derive other kinematics formulas from the definition formulas for average velocity and average acceleration.  After we derive these formulas, we can start using them for problems.  There are several reasons why we're doing this exercise... (1) It's important to know where these formulas we're using come from.  (2) It's important for you to know what I expect your solutions to look like for every problem - diagram, knowns & unknowns, accepted formula, algebraic manipulation to get an expression for the unknown, and finally a numeric answer.  (3) It's good practice for all the algebra we'll be using in this class.  We'll try to complete #1-3 on "It's Your Lucky Day" Packet during class. 
Homework:  No homework weekend.  By Tuesday:  Make sure you've completed #1-3 on "It's Your Lucky Day" Packet.  Check your Solution to #2 below.
