9-107.

The center of a figure is the shared vertex of 2 rays, labeled, 120 N, & 250 N, with the angle between labeled, theta.Two forces with magnitudes of N and N act on an object of negligible mass as shown in the diagram at right.  

  1. Determine the magnitude and direction of the resultant force if .

    The resultant vector can be found by computing: 

  2. Determine the magnitude and direction of the resultant force if .

  3. Determine the magnitude and direction of the resultant force if .

  4. Express the magnitude of the resultant force as a function of , where .

    The magnitude is the square root of the sum of each of the components squared.
