What is the inverse Laplace transform of $\sin\left[\sqrt{\frac{r-s}{D}}x\right]$, from $s$ to $t$

I was doing a exercise and I couldn't finish it because I needed to do this inverse Laplace transform, and I got no idea how to do it. I tried convolution, I expanded the sin to complex exponential and got nothing in the end. Can anyone help me?
