Time didn't permit video analysis. Maybe another day.

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.

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

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.
