Physics expert Christopher Manning prompted us all to take our seats upon my arrival. He then pointed out the Daily Question and asked us to address it's prompting. It read as follows: **A** **ball is launched at a speed of 5.3 m/s. How high does the ball travel?** It was then solved for all to see:  -9.8m/s*s=(0m/s-5.3m/s)/t t=.54 s then........ ΔX= ½ at2+vit ΔX= ½ (-9.8m/s*s)(.54s)^2+(5.3m/s)(.54s) ΔX= 1.43 m  **
 * a=(vf-vi)/t



The class then drew an LMD and VT graph representing the problem. The VT graph had a negative slope and was in the first quandrant. The LMD showed us that the acceleration was negative with an arrow pointing downward and the velocity was positive with the arrow pointing upward. To add a stroke os fun (supposedly) Manning, with the assistance of a giant, launched a ball upward to test the problem.

At 12:05 Manning announced that night's assignments. The class was reminded that tomorrow they would have a test on word problems, LMDs and VT graphs tomorrow. He encouraged the students to complete pages 43 and 44 because he claimed "doing practice problems is the best way to study...it's been proven!" (Manning). In addition, the extra credit accelerometer construction is due tomorrow along with page 42 - Create Your Own Problem. Remember: Problems that are extra-creative and thought provoking will receive additional extra credit at Mr. Manning's discretion. The last 15 minutes were awarded to the class for individual practice and problem completion. Tomorrow's test will be approximately twenty points.
