1. The problem statement, all variables and given/known data http://img252.imageshack.us/my.php?image=heyheygw0.jpg Mass=57.1 Kg Distance 69.5 m G= 9.8 Theta= 34.9 So I'm trying to find the amount of work done on mass. 2. Relevant equations F=ma Work=Fcos(theta)D 3. The attempt at a solution Okay so i started out finding Force by newtons 2nd law. F=ma f=57.1(9.8) F=559.58 Okay so then I went with force to the work fomula. Work=559.58cos(34.9)69.5 and that gave me 31896.37 but this answer proved to be incorrect?
