Today in physics we started the class off by having each group make final adjustments to their presentations about Barbie Einstein. We then proceeded by having each group present their story on how Barbie Einstein died. There were a wide variety of theories to how Barbie died, but Hunter's Scooby-Doo story was by far the most creative. We found out that the time was 2.1 sec and the horizontal velocity was 7.3m/s. After the presentations, Coats-Haan shared the truth about Barbie Einstein's death. Coats-Haan then gave us two follow-up questions about Barbie Einstein which we were told to write on a piece of notebook paper. The first was about what questions the Grand Jury should ask and about our assumptions, and the second was how high Barbie would have had to have started in order to land in the pool. If we finished we could turn the questions in. Three worksheets were handed out at the beginning of class: The Case of the Scientific Aristocrat, the HAC check, and The Non-Linear Motion Test Review. The Case of the Scientific Aristocrat goes along with page 53 in the lab manual and is due Wednesday. The HAC check is due Thursday, and the Non-Linear Motion Test Review is due Friday. The Dart Gun Lab Reports are due tomorrow.
QOD: The fastest person in the world has ran about 23mph. 8m/s converts to 17.89mph, so a person can run 8m/s. It is not a walking speed because a walking speed would not be as fast as 8m/s. The average walking speed for a woman is 3mph which is not nearly as fast as 17.89mph.
