Today, we'll test your Ladder Lab models with a few questions.  One of the other groups will test your model and give you feedback.  You'll go through the iterative process of engineering your ladder model to correct any weaknesses.  You'll answer a few more questions to make sure your model works well.  Finally, you'll answer the ultimate question about the real-life safety of ladders by researching some specifications of real ladders and you'll consider some design choices that could make the ladder safer.    

Homework:  Watch the video below on center of mass:

Period 4 only:  If you haven't taken calculus yet, really try to make sense of the time derivative and integral stuff in previous videos.  Watch the following video on how to solve kinematics problems with calculus.  Everyone should at least browse this video so we make sure we're all on the same page.  Clarification:  Make sure your function is a continuous function before you try to integrate.
