Hello fellow students today was my TPJ the pablo peguero and here’s how it goes. The day started off with a daily question, well more like a homework check. As usual my weekend plans didn’t allow me time to complete my homework, so I guess I will be taking a zero for the assignment. A few minutes were taken to explain the homework problems. All homework problems can be found on page 28-30. Number 5 was explained in detail. A list of conservative forces is expected to be remembered. Problem number 1 was examined. Time was wasted as Mr. Manning harped on one girl for a good 3 minutes trying to get an answer. Mr. Manning finally got feed up with me talking in class and i was moved to a seat at a lab table in the back of the classroom. We started talking about of all things, roller Coasters. We started a lab dealing with a “k’necs” roller coaster. The point of the lab was to figure out the amount of energy that is lost during the cart’s down hill decent. I guessed that 90 percent of the energy would be lost rolling down the hill. Matt went to the front of the room and measured the height of the tracks. Some kind of fancy laser type thing measured the spend of the cart as it came down the hill. The rest of the problem was solved….over 50 percent of the energy was lost.
