Below is to be completed in class what is not completed should be done for HW due next class.
 * Measurement/graphing Lab (due next class)
 * Answer the following question to be collected next class. Show all work!
 * The estimated US debt as of August 26, 2012 is $15,998,000,000,000. Estimate the depth of stacks of $100 bills completely covering a NFL football stadium 100yds long and 160 feet wide (excluding end zones).
 * a) The estimated US population is **314,300,00** people. If everyone contributed to the debt what is each person's share?
 * b) If the average American household (assume 4 people) is $46,326 (www.mybudget.com), how long would it take to pay off this debt.

@Speed and Velocity Part 2 )
>> What is the class average? Submit your walking speed on the Part 2 form above.
 * Derive 2 equations relating position, time velocity and acceleration 1st eliminating time then final velocity. Both equations are to be derived in under 5 minutes without skipping steps.
 * Speed Activity A
 * Determine your walking speed in m/s and miles per hour.
 * Problems:
 * Ch 2.2-3Average and Instantaneous Velocity
 * #1, 2, 4, 5-11 odd & 12,
 * Here are the derivation videos for your review Ch2 Derivations

2.6 One dimensional Motion with Constant Acceleration
 * 1) 23-25 all, 27-30 all, 31-35 odd,

__** September14/18 **__
__** Objective. **__** //Use linear motion equations to solve complex problems.// ** Complete September 12 & 13 Problems listed below again. Derive the 2 linear motion equations in under 5 minutes showing all steps in the process. (Collected) Hw will be checked. for completeness on Sept 19/20.

Review and complete text problems below. Review Flip book project. How can one accurately place objects on small sheets to represent acceleration?

Design a lab experiment to determine the free fall rate of acceleration by dropping a tennis ball down the stairwell. What would you measure? How would you analyze the data? What graphs would you generate and why? What do you anticipate them looking like?

2.4 Acceleration #16-18, 20 2.6 One dimensional Motion with Constant Acceleration
 * 1) 23-25 all, 27-30 all, 31-35 odd,

Watch video Free Fall (this video is not up yet)
Determine the rate of free fall acceleration as a class by dropping tennis balls in the north stairwell from different heights. We will measure the heights from the ground floor to each of the 8 floors and time the each drop 2-3 trials. From knowing the distance, initial velocity, and time we will work to determine the rate of acceleration Using data analysis and graphing.

Start Ch 2.7 #37-41 all, and 43

__** September 21/24 **__
Determine your reaction time knowing the rate of acceleration. Describe free fall and use to analyze 1 dimensional motion in free fall. 2.7 Freely Falling Objects

Conceptual Questions: #1-15 odd and 6 & 12 Recitation Review for 1st Test.
