Question description

  1.  The displacement vector A⃗ and B⃗ (as shown in Figure P3.11) both have magnitudes of 3.00 m. The direction of vector A⃗ is θ = 30.00◦ . Find graphically (a) A⃗ + B⃗ , (b) A⃗ − B⃗ , (c) B⃗ − A⃗ , and (d) A⃗ − 2B⃗ . (report all angles counterclockwise from the positive x axis.) 

A force F⃗ 1 of magnitude 6.00 units acts on an object at the origin in a direction θ = 30.0◦ above the positive x-axis (see Figure P3.10). A second force F⃗ 2 of magnitude 5.00 units acts on the object in the direction of the positive y axis. Find graphically the magnitude and direction of the resultant force F⃗ 1 + F⃗
