Question $9(5$ points$)$

The position of an object that is oscillating on a spring is given by the equation $x=(17\mathrm{.}4cm)cos[(5\mathrm{.}46s^{-1}{)}^7].$ What is the angular frequency for this motion?

$2\mathrm{.}34ra\frac{d}{s}$

$0\mathrm{.}183ra\frac{d}{s}$

$5\mathrm{.}46ra\frac{d}{s}$

$17\mathrm{.}4ra\frac{d}{s}$

$0\mathrm{.}869ra\frac{d}{s}$
