Physics quiz corrections and the first Winter IDEAl solution are both due next Wednesday, Jan. 31.
For quiz corrections, please use the fresh, slightly revised copy of the quiz posted here.
The problem for the IDEAl solution is based on the 3rd quiz question but with one small addition. To get a sense of whether your answer to the new part is reasonable, you might compare with this video of a system based on the same principles at work on the International Space Station (fast forward to 1:45 if you want to skip to seeing it in action).
For a refresher on what my rationale and expectations for the assignment are, please review the post from Fall quarter where I explain both.
