This is my first physics class and I'm looking to do more than just pass it, I want to understand everything fully. Anyway, my class just started going over Newtons first, second and third laws, and I'm having trouble with a problem in my book (this problem http://img290.imageshack.us/img290/9241/physhelp1gi.jpg [Broken]. I've scanned both the question, and the solution from the solution manual. When I think about this problem, I must be over simplifying it, because for part (a), I thought the tension would just be the weight of M2 minus the force of m1, but it doesn't seem that way. As for parts (b), (c), and (d), I'm completely lost. This problem is not for credit. I asked my teacher for help, but I still didn't understand him. I'm hoping someone here can explain this to me with words and math rather than just math, because it's easier for me to understand it that way. Thanks.(adsbygoogle = window.adsbygoogle || []).push({});
