A force F1 of magnitude 6.00 units acts on an object at the origin in a direction theata=30 degrees above the positive x-axis. A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Required:
Find graphically the magnitude and direction of the resultant force F1+F2.
