A force vector F1 points due east and has a magnitude of 200 newtons. A second force F2 is added to F1. The resultant of the two vectors has a magnitude of 400 newtons and points along the east/west line. Find the magnitude and direction of F2. Note that there are two answers.
i don't get the question, what it means by "points along the east/west line",how come it would has two answers?
PLZ HELPPPPPPPPPPP, THANKS A LOT!!!!

bobpursley,
I will give you one hint....
F1+F2=+400E
F1=100E
solve for F2.
