Problem 39E

Vector $$\overrightarrow{\boldsymbol{A}}$$ is 2.80 cm long and is $$60.0^{\circ}$$ above the $$x$$-axis in the first quadrant. Vector $$\overrightarrow{\boldsymbol{B}}$$ is 1.90 cm long and is $$60.0^{\circ}$$ below the $$x$$-axis in the fourth quadrant (Fig. E1.39). Use components to find the magnitude and direction of (a) $$\overrightarrow{\boldsymbol{A}}+\overrightarrow{\boldsymbol{B}}$$ ; (b) $$\overrightarrow{\boldsymbol{A}}-\overrightarrow{\boldsymbol{B}}$$ ; (c) $$\overrightarrow{\boldsymbol{B}}-\overrightarrow{\boldsymbol{A}}$$ . In each case, sketch the vector addition or subtraction and show that your numerical answers are in qualitative agreement with your sketch.
