Homework Equations
The Attempt at a Solution
I drew it like this.
[PLAIN]http://img684.imageshack.us/img684/3453/draww.png
So I got the 18N by doing 53-35 for the top line which is moving in the west direction.
So to find the Fnet I did x= 422 + 182
So Then I got x = 1764 + 324
x=2088
then square root it I got 45.7 N... I am wondering if this is the correct Fnet or I did it wrong?
Also wondering if I need to also put the theta by doing...
tan-1 18/42 then its 23.2 degrees then I don't know the direction like N of e or s of w. Not sure if I need the theta though or just the fnet in Newtons.
thanks!
