To simplify \(-15 \sqrt{y^2}\), we start by noting that since \(y > 0\), the square root of \(y^2\) is simply \(y\).
Therefore,
\[
\sqrt{y^2} = y \quad \text{(since \(y\) is positive)}
\]
Now, substituting this back into the original expression:
\[
-15 \sqrt{y^2} = -15y
\]
So, the simplified expression is:
\[
\boxed{-15y}
\]
Therefore,
\[
\sqrt{y^2} = y \quad \text{(since \(y\) is positive)}
\]
