PPH $103$: FINAL: Version B

A vector vec$(A)$ has components $A_x=5\mathrm{.}0m$ and $A_y=12\mathrm{.}0m.$ What is the angle that vector vec$(A)$ makes with the $x-$axis?

A$)12\mathrm{.}6$

$($B$)22\mathrm{.}6$

$($C$)32\mathrm{.}6$

$($D$)67\mathrm{.}4$

$($E$)6.$

Vector vec$(A)=6\mathrm{.}0m$ and points $30$ north of east. Vector vec$(B)=4\mathrm{.}0m$ and points $30$ east of north. The resultant vector vec$(A)+$vec$(B)$ is given by

A$)0\mathrm{.}7$ m at an angle $42$ north of east.

$($B$)13\mathrm{.}7$ m at an angle $42$ nerth of east.

$($D$)9\mathrm{.}7$ m at an angle $42$ north of e

C$)1\mathrm{.}1$ m at an angle $42$ north of east.

E$)2\mathrm{.}0$ m at an angle $42$ north of east.
