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.
 
If A is a vector which makes an angle θ with the x axis, what is Ax and Ay?
