![## Problem: Calculating the Mass of a Wire on a Parametric Curve
**Question:**
Find the mass of a wire that lies along the curve \(\mathbf{r}(t) = \left( t^2 - 9 \right) \mathbf{i} + 2t \mathbf{k}, \, 0 \leq t \leq 3\), if the density is \(\delta = \frac{3}{2} t\).
---
**Solution Template:**
To calculate the mass of the wire, we use the integral:
\[ \int_C \delta(x, y, z) \, ds = \boxed{\text{Answer Here}} \]
