Physics Exam Instructions You may work together on this exam to solve proble ms. You may talk to us about the problems. You may post on blackboard and ask about problems. You should not work with people outside of classto solve any problems Solution should include motion diagrams and graphical necessary. Solutions should be written clearly and concisely. It might be wise to include instructions at points in your solution. Very importantly you must write your own explanation describing the physics of the solution to the problem. It is really appropriate to reference you solution in your essay-they are not independent The essay is to be your work alone. You should justify any assumptions and describe the impact of these assumptions (if they are wrong or used purely for achieving a simple solution). You need not xplain the math, only the physics. You must include results in your essay. We do not want to have to refer back to your work to get the answer. THE ESSAY MUST STANDALONE! When talking about a situation, the associated pictures and diagrams must be there so that the reader need not jump around in the document. You are trying to PLEASE the reader (also known as the grader). There will be the need to do some research to get masses of objects, reasonable sizes,coefficients of friction, etc. as needed to solve a problem. Grading All solutions will have the 30 second rule applied. The 30 second rule means that if the grader cannot figure out what you are doing in 30 seconds, you get a zero. Not drawing proper diagrams with proper labeling, inappropriate use of vector signs, and lack of units will get an additional 1 point per occurrence deductedExplanation / Answer
by adding the weights spring expand. its not attached at the centre so the exapantion is not symetric so that it streches the platform as a wedge shape due this he can move fastly as before
