I don't think it was very nice that you wouldn't actually solve the problem for me. The professor did not teach it, there are no similar problems or formulas in the textbook and its not hw. The test was today and I had to pretty much leave that one unfinished. Anyway I would still like to learn...
Do you know how to solve the problem? It would help a lot if I saw it done. I am pressed for time and have 3 exams tomorrow and this is one question i was not sure of for my physics exam.
Thats just it, I don't know the formulas...It would help me if I saw it done by someone else with the formulas this way I have some time to studyit before my test tomorrow..it was one of two out of the 20 questions I was unable to get. I would be able to break the formula down if I saw it done.
