The displacement vectors A→ and B→ shown in the figure below both have magnitudes of 4.20 m. The direction of vector A→ is θ = 21.0∘. (a) Find A→ + B→ graphically. magnitude m direction - counterclockwise from the +x axis (b) Find A→ − B→ graphically. magnitude m direction - counterclockwise from the +x axis (c) Find B→ − A→ graphically. magnitude m direction - counterclockwise from the +x axis (d) Find A→ − 2 B→ graphically. magnitude m direction - counterclockwise from the +x axis
