The position function $x=(4\mathrm{.}0m)cos[(2ra\frac{d}{s})t+\frac{}{3}$rad$]$ gives the simple harmonic motion of a body. At$=2\mathrm{.}0$ s $,$ what are the $($a$)$ displacement, $($b$)$ velocity, and $($c$)$ accleration of the motion? Also, what ane the $($d$)$ amplitude, $($c$)$ frequency and $($ f $)$ period of the motion?
