Special Announcements

• IMPORTANT: There will be no equations given on the exam. Instead, you can bring a 5x8 index card that you have filled with any information you like. Index cards will be available to pick up in class on Wednesday, and after that in the handout room.
• There will be an optional review session for the final on Saturday Dec 15, room 6-120, 4-6 pm (note not the usual place).
• Prof. Scholberg will be out of town on Thu and Fri, but will have special office hours from 1-5 pm on Sunday in 4-149 (note: not the usual place!). Please come by with any last minute questions!!
• Subject matter covered for the final: basically everything, with some emphasis on the later material. There will be two experiment questions, and you can expect at least one of these to be on AM, or Flow reanalysis. Subject list: estimation, 1D and 2D kinematics, projectiles, Newton's Laws, friction, spring forces, uniform circular motion, torque and statics, work, kinetic and potential energy, conservation laws, simple harmonic motion, impulse, momentum, center of mass, collisions, angular momentum, moment of inertia, angular kinematics and dynamics, elastic properties of solids, fluid statics and dynamics.
• There are no more CyberTutors due for credit, although there will be lots of review problems. However, there is one special optional CyberTutor assignment due Sunday, for extra credit. The purpose of this assignment is to help develop new standardized tests for freshman mechanics. It should take less than an hour to do. Please do it by yourself. The problems are short, and each correct answer is worth 1 point which will be added as a bonus to your overall CyberTutor score.
• Please note a typo in PS #12, problem 3: should read 0.6 kg, not 6 kg.
• About 8.02X: Anyone currently enrolled in 8.01X who preregisters by December 28 is guaranteed to be enrolled in 8.02X. Please note that students who do not pre-register on time will be treated like non-8.01X students in terms of being placed on a wait list etc.
• You must return all the equipment in the Red Box and experiment parts kits in order to get a grade for 8.01x. If you haven't returned it yet, please bring it by after class. It's OK if you are missing some of the small parts and non-reusable items, but you absolutely must return the bigger items listed here. The black tool kit is yours to keep.
• Tutoring hours this week: Fri Dec 14 2-4 pm.
• The class average on quiz 3 was 74/110, and passing grade is defined to be 50/110, or 45%. Please note that the quiz is out of 110, but it will be weighted equally with the other quizzes for your final grade (in other words, it's your percentage grade on the quiz that counts for the 15% of the grade). The final exam will be worth 25% of your final grade.
• Change to Prof. Scholberg's office hours: due to conflicts with other freshman classes, Wed hours are now changed to Tue. New schedule: MF 11-12 am in 4-338A, and Tue 10-11:30 (and sometimes until noon, if there are people around), plus, as always, by appointment. Office hours are held in 4-338A, except for Fridays on weeks when a lab check-off is required, when they will be held in 16-168. Recitation instructors' office hours can be found here. Note that you can go to an instructor's office hours even if you are not in his or her section.
• The Final Exam will be Monday, December 17, from 9AM - Noon in Room 10-250.
