Welcome to [math.se] SE. Take a [tour]. You'll find that simple "Here's the statement of my question, solve it for me" posts will be poorly received. What is better is for you to add context (with an [edit]): What you understand about the problem, what you've tried so far, etc.; something both to show you are part of the learning experience and to help us guide you to the appropriate help. You can consult this link for further guidance. – Martin R Jun 27 '22 at 19:44

It's literally the definitions of inverse Laplace. No calculations are needed. The answer is
\begin{align} 5 \delta (t) + \cos (3t) \end{align}
