The displacement vectors A and B shown in the figure below both have magnitudes of 3.21 m. The direction of vector A is
8 = 29.9°
(a) Find A
(b) Find A - B graphically.
(c) Find B - A graphically.
(d) Find A 2B graphically.
B
Step 1
Visualize adding vectors as playing golf. You string along one displacement after another, each beginning where the last
ended. Visualize the negative of a vector as an equal-magnitude vector in the opposite direction. Visualize -2B as having twice
the length of B and being in the opposite direction.
Step 2
We must draw with a protractor and ruler to construct the additions. Then we must measure with the ruler and protractor to
read the answers.
Step 3
To find these vectors graphically, we draw each set of vectors as in the following drawings. We have a free choice of starting
point and of scale. When subtracting vectors, we use A - B = A + (-B). (Note: the vector addition in the figures below use an
arbitrary value of that may not match your randomization.)
