Homework Help: Physics 11 vector question?

  1. Feb 7, 2009 #1
    1. The problem statement, all variables and given/known data

    50N , 75N [N], 40N [W], and 55N [E] all act on a point. what is the resultant force?

    2. Relevant equations



    3. The attempt at a solution
    I tried making w and s negative and n and e positive but that gave me 40N and the answer should be 29N, 59[tex]\circ[/tex] N of E . help plz??

    Hello,

    I'm not sure how you got 40N [North?] but you have to perform vector addition. Basically, think of the vectors in terms of x and y components, with, like you said, S and W being negative, and you'll get an answer with both x and y components, so you have to figure out the angle it makes.
