Momentum in 2D lab revised expectations

I didn't expect the data analysis section of the lab being as hard as it was.  Due to time constraints, I'm going to alter the lab expectations.  You still need to write the background section, conclusion and error analysis, but I have created and analyzed a set of data - calculations and vector diagram.  You may use mine.  I'll have it for you on Monday.  If you've already done the data analysis on your own, you can use your own and get 5 extra credit points.
