The given problem asks to find the **Inverse Laplace Transform** of:

\[
\frac{s}{(s+2)^2 + 4}
\]

This expression resembles the standard form for the Laplace transform of a cosine function with a phase shift. The general formula for the inverse Laplace transform of:

\[
\frac{s - a}{(s - a)^2 + b^2}
\]

is:

\[
e^{at} \cos(bt)
\]

### Steps to Solve:
1. First, notice that the given expression can be written in a form similar to the above template:
   
   \[
   \frac{s}{(s + 2)^2 + 2^2}
   \]
   
   Here, \( a = -2 \) and \( b = 2 \).

2. Using the formula, the inverse Laplace transform is:

\[
\mathcal{L}^{-1} \left( \frac{s}{(s + 2)^2 + 4} \right) = e^{-2t} \cos(2t)
\]

### Final Answer:
The inverse Laplace transform of \(\frac{s}{(s + 2)^2 + 4}\) is:

\[
e^{-2t} \cos(2t)
\]
