The graph shows the variation of the water level relative to mean sea level in Commencement Bay at Tacoma, Washington, for a particular 24-h period. Assuming that this variation is modeled by simple harmonic motion, find an equation of the form
y = a sin(ωt)
that describes the variation in water level as a function of the number of hours after midnight.

We are given with the simple harmonic motion equation
y = a sin(ωt)
a is the amplitude which can be obtained from getting the highest water level with respect to the mean water level.
ω can be obtained by taking the period of the changing water level. If T is the period then,
ω = 2π / T

The amplitude of the equation is the maximum water level and the value of w is the period of changing water level.

Further explanation:

The function is periodic and the equation can be expressed as follows,

[tex]\boxed{y = a\times\sin\left( {wt} \right)}[/tex]

Here, a is amplitude of the function, period of the function is [tex]wt.[/tex]

Given:

The period of the function is 24-h.

Explanation:

The simple harmonic motion equation is given as follows,

[tex]y = a\times\sin \left( {wt}\right)[/tex]

“a” is the amplitude of the function and can be obtained from the highest level of water in respect of the mean water level.

The value of w can be obtained from the change of water level.

[tex]w =\dfrac{{2\pi }}{T}[/tex]

The amplitude of the equation is the maximum water level and the value of w is the period of changing water level.
