Question

In certain physical models, the no homogeneous term, or forcing term, g(t) in the equation at”+by’+cy=g(t) may not be continuous, but have a jump discontinuity. If this occurs, a reasonable solution can still be obtained using the following procedure. Consider the following initial value problem.

## Initial Value Problem

We are given the following differential equation and conditions:

\[ y'' + 8y' + 32y = g(t); \quad y(0) = 0, \quad y'(0) = 0, \]

where $ g(t) $ is defined as:

\[
g(t) =
\begin{cases}
128 & \text{if } 0 \leq t \leq 5\pi/4 \\
0 & \text{if } t > 5\pi/4
\end{cases}
\]

### Tasks

Complete parts (a) through (c) below.

#### (a) Find a solution to the initial value problem for $ 0 \leq t \leq 5\pi/4 $.

The solution for $ 0 \leq t \leq 5\pi/4 $ is $ y(t) = $ \_\_\_.

(Note: Insert the appropriate solution equation into the blank space once calculated.)

This problem involves solving a non-homogeneous second-order linear differential equation with given initial conditions and a piecewise function $ g(t) $. The process typically involves finding the complementary solution from the homogeneous equation and a particular solution that satisfies the non-homogeneous part.
