I have a problem here. That I believe, I have half way figured out.
Here is the problem shortened.
Force A has a magnitude of 465 Newtons and is directed due west.
Force B has a magnitude of 350 Newtons and is directed due north.
I have to find the magnitude and direction of the resultant force A + B.
So what I first did was draw a triangle that looks like the one below.
I used the formula R = (The sguare root of) A^2 + B^2. To find the resultant. Was that correct? If so my answer was R = - 582 Newtons. If not, then I'm back to the freaking drawing board.
I then needed to find the degree of the angle. Pointed out in the other attachment. For that I used the formula: theta = sin^-1 (ho/h).
So my answer for that was 37 degrees south of west. Did I do the right thing here? Did I even find the right angle?
One of my biggest problems is figuring out what formual to use to find the angle I need. And how to figure out what angle it is I need to find.
I would appreciate any help that would be provided.
Thanks in advance
