# Fall 2016 Mechanics Week 11

Wow, last week of classes. We will review material while exploring new questions. Additionally, we will add trigonometry and you will be allowed to use the two kinematic formulas that most classes introduce in the first week of classes, now that you are able to solve questions without these formulas.

Tuesday

first hour
Before Class

• Surveys: Please take the university survey for this class. The link was sent to you via Email.
• See Trigonometry Video , now you’re allowed to use trigonometry, but remember you can also always draw a picture if you’re not sure.
• See and then you’re allowed to use those two unhelpful (in my opinion) equations, although hopefully, you’ve realized by now that you can get along without them just fine.
• Watch this video: Spinning Skater What are the forces on a skater’s arms when she is spinning very fast?
• I watched the videos. I liked all of them and all of them have something more I’d like you to do this week. Please see the second project webpage and read my comments. Also feel free to read the comments I made to other videos and watch the other students’ videos if you like.
