TBA Final Exam (comprehensive)

COLLECTED HOMEWORK

The purpose of the collected homework is two-fold: (1) to enhance your problem solving skills; and (2) to enhance your communication skills. You must get at least a 65% on the collected homework to pass the course! The collected homework (which counts as one of your nine [or ten] grades) consists of a set of 9 problems of which one problem will be due most every Wednesday (see schedule below). Each problem will be worth 11 points giving a total of 9 x 11 = 99 points. If you get the required 64 points (or more), I will add a point to your grade to make the homework grade be based on 100 (like all the others). If you do not turn in the problem by the due date, you may turn it in before the last day of class but there will be a late penalty of 2 points. If minor errors (e.g., dumb algebra mistake, incomplete units, occasional grammar error) are detected, points will be subtracted. If major errors are detected (e.g., few if any units, unclear diagram, start with specialized equations rather than basic equations), the problem will be marked REDO and no credit will be awarded unless it is redone in an acceptable manner and resubmitted by the last class (on April 18). Problems will normally be returned to you at the next class so that you have time to correct the major errors. If you get any grade less than 9 on any problem, you may re-submit that problem before the last class for up to 9 points credit.

Format for regular collected homwork:

The collected homework must be done according to the following format: [BE SURE TO NUMBER EACH OF THE SEVEN STEPS FOR EACH PROBLEM.]

  1. I want to and I can : State this at the beginning of the problem. Questions you should ask yourself to confirm this attitude include: Do I want to pass the course? Do I want to learn something? Do I want to see how well I know something and understand the concepts? Have I read the chapter? Have I reviewed my notes from class? Am I willing to seek help?
  2. Define the situation : a) State what you are given (for each piece of information define a symbol and then set that symbol equal to the value you are given). b) Draw a diagram and put your knowns and unknowns on the diagram. I consider this VERY IMPORTANT!
  3. State the objective : a) State what you are looking for (use a symbol or symbols that will be found in the equations you will use and define those symbols). b) State what units the quantity or quantities should have.
  4. Explore the options : a) State the basic equations or principles (by name only) that could be used. Note: only definitions or equations on the study guide are allowed. b) State any other way you might accomplish the objective.

SAMPLE COLLECTED HOMEWORK PROBLEM

  1. I want to and I can.
  2. Define the situation : a) Given: length of person, yperson = 6 ft; mirror. b) Diagram : mirror ytop top eye yperson y 2 refl. yshoes = 6 ft y 1 inc. bottom x
  3. State the Objective : a) Looking for useful length of mirror, yused b) Units: length should have units of feet.
  4. Explore the Options : a) Equations: incident = reflected (law of reflection) Eq. (1) tan  = opposite/adjacent (trig def.) Eq. (2) yshoes + ytop = yperson (def. from diagram) Eq. (3) b) Other ways: obtain a long mirror and have someone mark on the mirror where you see your shoes and where on the mirror you see the top of your head.
  5. Plan the method of attack : draw lines from eyes to mirror and back to shoes such that incident = reflected. Find position on mirror where ray of light from shoes strikes on way to eye; repeat procedure for top of head. Measure distance between these two points. (Any portion of mirror below the first point or above the second point is not useful for present purposes.)
  6. Take action : (a) draw lines from eye to mirror and from mirror to shoes; (b) identify incident and reflected; note that incident = reflected; (c) extend normal line used to specify 's to create two triangles; (d) from diagram, note that since incident = reflected (Eq. 1) that tan incident = tan reflected ; therefore y 1 /x = y 2 /x (using Eq. 2); (e) therefore, y 1 =y 2 ; and since y 1 +y 2 =yshoes , y 2 =½yshoes; (f) the same procedure can be used for the distance needed for the top of the head; (g) therefore, yuseful = ½ yperson = ½ 6 ft = 3 ft.
  7. Look back : a) Answer: yuseful = ½ yperson = 3 ft. b) Units are in feet which corresponds to 3b. c) The useful length depends on the height of the person which is reasonable. yused

COMPUTER ASSIGNMENTS

The purpose of the computer assignments is two-fold: (1) to give you (graded) practice applying the concepts taught in class (with immediate feedback as to whether you are correct or not), and (2) to encourage you to be accurate in your calculations (no partial credit given for wrong answers - instead a chance to do the whole set again [but with different numbers]). The computer homework set, which will count as one of your ten grades, consists of 11 separate computer programs (schedule is on the next page). To do any of the programs

  1. Go to any pc that has a connection to the web, or see your instructor about making your own copy on your own memory device. a) From a pc with an internet connection, you may download the programs from the net: see the PHYS 202 page on the net or the physics home page on the net: http://www.cbu.edu/~jvarrian/downcbu.html. b) If you have copied the programs onto your own memory device, then place the device in drive d (or e), press the START key, choose the RUN command, and type a:\PV3 (and Enter) for Vol. 3 or type PVn (and Enter) for Vol. n (see schedule below).
  2. After you start the programs, the computer will ask you to verify the disk and directory that the answers will be written to. For your own device, make sure that destination is d:\ (or e:\ if you put the disk into drive e). If you want, you may e-mail the responses by attaching the file: STRES.DAT to an e-mail message. NOTE: You may copy the programs to your hard drive and run them that way rather than from your memory device. You can also choose to store your answer file on your hard drive - simply choose the appropriate directory on that first message when the program begins to run. You will need to either e-mail the response file (called STRES.DAT) to me or you will have to copy that file to your memory device and bring it to me that way, so be sure to keep track of where this file is located.
  3. Enter your course number [PHYS 202, choice c], then your instructor [Dr. Holmes, choice h], then your section [A, choice a], then enter your name: Last First (use no commas). The computer will then ask you to verify your course and name - if it is correct as displayed, simply press return; if not, re-enter in the course or name.
  4. The computer will then display the menu of programs on the volume you have chosen. Simply type in the number of the program you wish to run and then press Enter to confirm your choice. From here on out, simply follow the directions on the screen.
  5. How I read your responses: You will have to submit the student response file (STRES.DAT) either on a memory device or by e-mail attachment (send e-mail to jholmes@cbu.edu) by the due date so that I can read your responses and give you the appropriate credit.
  6. I will indicate to you your current computer score on your written homework and on your tests when I hand these back to you. There will be a CH followed by a number on the written homework or test to indicate your computer homework score. Each of the programs asks questions or allows you to do certain things. Your answers or results are recorded on the diskette as you do them. This allows me to grade your computer homework. Each assignment may be performed as often as you like. I will only count your best effort, so feel free to do it over and over until you get it perfect. The due date indicates when it should be completed if you are to remain on schedule and wish full credit. If you do the assignment after the first due date and before the final exam, you will get 80% credit.
