1. The problem statement, all variables and given/known data http://go.hrw.com/resources/go_sc/phy/HF2SR042.PDF this is the link to the worksheet im having trouble with. if anyone could help me out that would be great. i got most of it but have a few questions. 2. Relevant equations fy=sin(angle) x force fx= cos(angle) x force fnet = √(fy^2 + fx^2) 3. The attempt at a solution 1.) F1 + F2 + F3 2.) String 1: x component:0 y component: -Fg String 2 x component: -F2cos(theta1) y component: F2sin (theta1) String 3: x component: F3cos(theta2) y component: F3sin(theta2) Number 3 is what im having trouble with. i know that the Fx net is: √0+xcomponent String2^2+x component String3^2) but im not sure about the y component. is it just the sqrrt of the sums of the squares of the three ycomponenents? or am i missing something? oh and i think i can do #4 without a problem. so can someone check my work and make sure its right and help me with #3? thanks!
