Exam Question #1 for time.

Hey tired of opening stuff that you didn't want in the first place?
Thinking about how much you just wish you could get some you time.

Tell em your sadistic physics teacher gave me a problem today due today.

• Do at least 3 multi body problems from the book.
• Check the answers to make sure you have the skills to proceed.

• Click on the link.Exam Question #1 for time.
•   Set the timer for 13 minutes.
• Work on the problem for the 13 minutes. 
•  When the bell tolls for thee.  Draw a line and complete the problem.  Or switch to a different color pen or pencil, that you may or may not have gotten in your shoes, or stockings or duct taped to your festivals pole. (Basically record where you were after working on the problem for the time allotted)
• Post comments.  You absolutely should have a good idea about how to solve this.  If not you need to post questions.   Remember there is a physics way and a math way t approach these type of problems.  Knowing and understanding both will be the most beneficial.

FBD REVIEW

Exam Tip

12. I would recommend that students practice working at a pace that is comparable to the AP PHYSICS 1 time frame. For example, if you know the AP test is 6 Free Response problems over the course of 90 minutes, then practice doing 1 Free Response problems in a span of 90 minutes divided by 6 problems. The worst scenario is a student not understanding the pacing needed to adequately work through the test.

QUADRATIC

program the quadratic formula.

Use the video to program your calculator.  Free questitio grade if you have done this when we return...
  I will give you a quadratic and you can use your calculator to solve for the roots...

FTL

• Calculate the equilibriant force for each case 1-4
• Do this both graphically and algebraically.

Note:  For some cases you get to choose one of the other forces.
Vector diagrams should be drawn to scale labeled and color coridinated.
You will need a protractor!  Or maybe not if you figure out another way to draw your vectors head to tail.
Here is a video on one method of translation
https://youtu.be/9KeW7onbX1Q
This is a method.   Ilf you discuss with your team you may come up with a better way to do it.  Think to previous labs.

FORCE TABLE ARE ONLY REQUIRED TO CHECK THE RESULTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

•  Check your results using the force table lab to attain equilibrium.  (If you are in class)
• Calculate the % error for the magnitude of your equilibriant.
• Report the absolute error for the angle.

Why would it be meaningless to calculate % error for your angle?  Think back to the first step in solving these problems...

A world-class runner can complete a 100 m dash in about 10 s. Past studies have shown that runners in such a race accelerate uniformly for a time t and then run at constant speed for the remainder of the race. A world-class runner is visiting your physics class. You are to develop a procedure that will allow you to determine the uniform acceleration a and an approximate value of t for the runner in a 100 m dash. By necessity your experiment will be done on a straight track and include your whole class of eleven students.
