Three displacement vectors of a croquet ball are shown in the figure, where $|vec(A)|=11\mathrm{.}0$ units, $|vec(B)|=60\mathrm{.}0$ units, and $|vec(C)|=40\mathrm{.}0$ units.

$($a$)$ Find the resultant in unit$-$vector notation.

vec$(R)=$ units

$($b$)$ Find the magnitude and direction of the resultant displacement.

magnitude unit$($s$)$ direction

counterclockwise from the $+x$ axis
