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.

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,

Here, a is amplitude of the function, period of the function is

Given:

The period of the function is 24-h.

Explanation:

The simple harmonic motion equation is given as follows,

“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.

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