A linear second-order non-homogeneous equation models this scenario: People falling at a height of 100ft above the ground attached to a 100-foot rope into a pit that's cut off at 75 feet underground. Spring constant of the rope is 120 lbs/ft, and air resistance is 5 times the instantaneous velocity. M is mass of person and g is gravity. Note that the pit is actually 100 ft deep, it's just cut off 25 ft from the bottom to make the pit 75 feet deep. What are the initial conditions of the height y(t) of the person falling at time t? The equation is my''+5y'+120y=mg The image contains a differential equation and some related notes and markings.### Differential EquationThe equation presented is:\[ my'' + 5y' + 12y = mg \]Where:- \( y'' \) represents the second derivative of \( y \) with respect to time, indicating acceleration.- \( y' \) represents the first derivative of \( y \) with respect to time, indicating velocity.- \( y \) is the position function.- \( m \) and \( g \) are constants, often representing mass and gravitational acceleration respectively.### DiagramThere is a horizontal line, which could represent an axis or base level. Above this line, the expression \( y(0) = \) is written, suggesting it is related to initial conditions for \( y \).To the left are three values stacked vertically:- \( 0 \)- \( 75 \)- \( 25 \)Each value has a horizontal line next to it, possibly representing levels or specific points of interest. However, without additional context, these numbers and lines could represent initial positions, thresholds, or other critical values related to the differential equation.

The objective of the question is to determine the initial conditions of the height y(t) of the…
