Thursday, 11-19-09:
  • In Class:
    • Finish AP Review w.s.
    • Finish PS 6.2: answers: 7.50, 19100, 364, 438, 5.3, 12, 8, 8, 5.3, 12
    • If time permits: begin video analysis of collisions.
    • Homework:
      • Two cars enter an icy intersection and skid into each other. A 2500 kg car going south at 20 m/s. A 1450 kg car driving east at 30m/s. The two vehicles become entangled and move off as one at an angle theta in a southeasterly direction. Determine both the angle theta, and the speed at which they skid away from the crash. We will assume the icy intersection has removed all friction.
Friday, 11-20-09:
  • In Class:
    • Went over the AP problem thing on that worksheet.
    • Went outside, a few people sat in a truck, we measured the height of the truck base-thingy to the ground each time someone went in. This was done so that on Monday we can use the data, put it in a chart, eventually figuring out the force on the springs.
    • We were done early and had extra class time to chill. WhAt?
  • Homework:
    • Read Chapter 5.4 Spring Potential Energy -- Focusing more on Hooke's Law and Elastic Forces
      • Take notes writing...
        • two new things that make sense... like "uh-huh, I get it!"
        • two new things that don't make sense to you... like "schmeh"?
        • Lastly, summarize the figures
    • Finish old HW that isn't done

Monday, 11-23-09:
  • Started work on Elastic Lab
    • Question for Elastic Lab:
      • What does the y-intercept represent?
      • Should the Y intercept be 0? Why or why not?
      • How would you change the y-intercept?
      • What does the slope represent?
      • How would you change the slope?
      • What are the units of measurement of the slope?
      • What is the spring constant of the truck?
  • Dan M What a guy.
