(II) V (→ above V) is a vector 21.8 units in magnitude and points at an angle of 23.4° above the negative 𝓍 axis.
(a) Sketch this vector.

Trace the vectors in FIGURE EX3.1 onto your paper. Then find $\overrightarrow{A}-\overrightarrow{B}$.

Trace the vectors in FIGURE EX3.1 onto your paper. Then find $\overrightarrow{A}+\overrightarrow{B}$.

(II) $\overrightarrow{V}$ is a vector 21.8 units in magnitude and points at an angle of 23.4° above the negative $x$ axis. Sketch this vector. 

Two perpendicular forces act on a box, one pushing to the right and one pushing up. An instrument tells you the magnitude of the total force is 13N. You measure the force pushing to the right is 12N. Calculate the force pushing up.
