Can someone point out where I am going wrong in this problem?
Three forces are applied to an object, as indicated in the drawing. Force 1 has a magnitude of 33.0 newtons (33.0 N) and is directed 30.0° to the left of the +y axis. Force 2 has a magnitude of 16.0 N and points along the +x axis. What must be the magnitude and direction (specified by the angle θ in the drawing) of the third force 3 such that the vector sum of the three forces is 0 N? magnitude28.6 Nθ2°
The only thing I need to do is find theta. I thought it would work by doing tan^-1(28.6) but that gave me 88 degrees and it didn't work. Suggestions?
