i have assignment in physics about graphical analysis of vectors...i need to see some examples or solution so i have any idea to do that..kindly help me pls..tnx
this is the question:
Make each vector on both numbers a reference vector then hylight w/color the polygon form...Using graphical analysis find the resultant of the following vectors acting on the object..

A=100 N,30degree NE
B=200N,80degree SE
C=150N,45degree SW
D=175N,25degree NW
E=50N due N

thats the question pls try to help me to answer it..tnx
N=north E=east W=west S=south

I have no idea what any of these mean. Can you give us the problem exactly as it's stated in your book?

You're going to have to do a better job of explaining what these mean. For example, in the first one you have A=100 N, 30degree NE. Is the first number the force in Newtons?

What is the significance of the part with degrees? In A 30 degrees is not NE; 45 degrees is NE. In the second, 80 degrees is not SE, which would be 135 degrees. In the third SW is 225 degrees, not 45. In the fourth, NW is 305 degrees.

You need to talk to your teacher about this. You use neither subtraction nor division. In fact, division of vectors is not even defined!
