needhelp1

1. The problem statement, all variables and given/known data
I need help with this hw problem.
1st vector: 80 N & 180 degree
2nd vector: 40 N & 145 degree
3rd vector: 50 N & -50 degree

And I need to find the resultant and the Eq. Where do I start and how do I do it please include answer as I'm confuse and I have a quiz on this soon. thanks

Hi needhelp 1, welcome to PF.
Do you know how to find the components of a vector along x and y axis?
If you know find the components and find ΣFx and ΣFy. Then find the resultant.

Thx for the quick reply! Can you guild me through? I don't understand this chapter. I was sick during the week due to a bad flu.
