In Problems 15-24, solve for $Y(s)$, the Laplace transform of the solution $y(t)$ to the given initial value problem. 23. $y'' + 4y = g(t)$; $y(0) = -1$, $y'(0) = 0$, where $g(t) = \begin{cases} t, & t < 2, \ 5, & t > 2 \end{cases}$

In this exercise, we will use the Laplace transform to solve the following initial value problem: y" - 2y' + 5y = 5, y(0) = 0, y'(0) = 2 First, using Y for the Laplace transform of y(t) (i.e., Y = L{y(t)}), find the equation obtained by taking the Laplace transform of the initial value problem. Next, solve for Y. Finally, apply the inverse Laplace transform to find y(t).
