Physics 1202W.100 Practice Quiz #4 December 7 th , 2012 Practice quiz #4 This is a closed book, closed notes quiz. Calculators are permitted. The only formulas that may be used are those given below. No other equation sheet is allowed. If any other modifications to the equations below were made or needed, make sure they are justified physically and explained as part of the solution. MAKE SURE YOUR NAME, ID #, and TAs NAME ARE ON EACH PAGE TO BE GRADED! Define all symbols and justify all mathematical expressions used. Please state all of the assumptions used to solve a problem. Credit will be given only for a logical and complete solution that is clearly communicated with correct units. Partial credit will be given for a well communicated problem solving strategy based on correct physics. Each problem is worth 25 points. For each problem it is expected that a picture (setup), procedure (what is the plan and physics involved), solution (the solution path and final answer) and evaluation (does it make sense, why or why not) is included. Each of the multiple choice questions is worth 5 points each.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
