[IMG]file:///C:/Users/bob%7E1/AppData/Local/Temp/moz-screenshot-2.jpg[/IMG][IMG]file:///C:/Users/bob%7E1/AppData/Local/Temp/moz-screenshot-3.jpg[/IMG]There are two forces on the 2.77 kg box in the overhead view of Fig. 5-31 but only one is shown. For F1 = 25.5 N, a = 13.6 m/s2, and θ = 20.6°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)

I can't page load error.... Sorry... it's a box with the known vector along the x-axis, and the unknown vector in the lower left quadrant. It's ok, I just figured it out, thanks a ton though, you guys are a great help!
