The position of a particle is given by the expression $x=4\mathrm{.}00cos(2\mathrm{.}00t+\frac{}{2}),$ where $x$ is in meters and $t$ is in seconds.

$($a$)$ Determine the frequency.

$1\mathrm{.}1$ Hz

$($b$)$ Determine period of the motion.

s

$($c$)$ Determine the amplitude of the motion.

$4\mathrm{.}1$

$$

$5$

$($d$)$ Determine the phase constant.

$$ rad

$($e$)$ Determine the position of the particle at $t=0\mathrm{.}350s.$

You know the equation giving the position of the particle as a function of time. How do you use that equation to determine the positic
