Seems like you can just determine the delta of your upward force(1000-500) and use it as the first leg of your diagram triangle, create a second leg with a 45 degree angle to the initial leg, and give it the wind's force of 300. Once you draw this, you should be able to determine the value...

So with it being a unit vector, r is = 1. This leaves me with the basic cos(45) & sin(45), etc... for their respective I+J values. I should be able to find the other solutions with trig functions as well. Awesome! Thanks for giving me a push in the right direction!

I have a question on an assignment that expects the I+J form of a vector but is only giving the direction(cardinal) or angle of the vector. See example below: Homework Statement Unit vectors and are directed east and north, respectively. Calculate the unit vector (in terms of I and J) in...
