Walking into class today we noticed that there were no papers that were to be handed in neither were there any papers that were to be collected from our folders. We did, though, have to place our "Another Detailed Analysis" on the table so that Coats-Haan could quickly come around and check for its completion. This detailed analysis was given to us the day before, and many of us completed it in class. Coats-Haan then asked the class if there were any questions concerning the detailed analysis, there were none and we moved on to a new and exciting task. Coats-Haan had, the day before, set up a scale model of a "crime scene" . In it was Barbie Einstein laying dead next to a hotel pool. She had fallen from the eighth floor, and we had to determine whether it was a homicide or suicide using our knowledge of projectile motion. Each table was given four minutes to approach the crime scene and take measurements. Our conclusion and measurements were to be placed on a white poster board and we are to present our findings to the class on Monday. Our homework was to complete our crime scene investigation. We also have a lab report due Tuesday, October 25th, and our quarter review as well as our projectile motion review packets are to be completed by Friday, October 28th.
Question of the day: How did you calculate Barbie's horizontal velocity when she left the hotel window?
To calculate Barbie's horizontal velocity you must first find her intial speed and then multiply that quantity by the cosine of zero.
