Asked by joy
he magnitudes are F1 = 1.81f,F2 = f,and
F3 = 2.00f,where f is a constant.
(a) Use the coordinate system shown in the figure above to find
R = F1 + F2 + F3
in component form in terms of f.
(b) If x = 0.25,
what is
Ry?

1st: To find R for part a), f1x,f1y,f2x, f2y, f3x, f3y.
2nd: f1x=0,f1y= -1.81, f2x=-.866,f2y=.500,f3x=1.00,f3y=1.73
3rd: To finf R, add all the fx together on one side and fy together on the other side.-->R=(0+-.866+1.00)i+(-1.81+.500+1.73)j
4th: answer of R-->R=.134i+.420j
5th: To find Ry for part b), we know Rx=.25i take it and divid by.134 and get .536
6th: answer for Ry,take .420 and divide by.536 and get .784 as answer.
