**Title: Calculating Tangential and Normal Components of Acceleration**

**Problem Statement:**

Find the tangential component \( a_T \) and the normal component \( a_N \) of acceleration at the \( t = 1 \) if 

\[
\mathbf{r}(t) = \langle 5t^{-1}, 3\ln(t), 7t^2 \rangle
\]

**Solutions:**

1. \( a_T(1) = ? \)

2. \( a_N(1) = ? \)

**Explanation:**

This problem involves finding the components of acceleration for a given position vector \(\mathbf{r}(t)\). The vector function \(\mathbf{r}(t)\) describes the path of a particle in terms of \(t\). 

- The tangential component of acceleration, \( a_T \), measures the rate of change of speed along the path.
- The normal component of acceleration, \( a_N \), measures the rate of change of direction of the velocity vector.

To solve this, you'll typically need to:

1. Calculate the velocity vector \(\mathbf{v}(t)\) by differentiating \(\mathbf{r}(t)\) with respect to \( t \).

2. Determine the acceleration vector \(\mathbf{a}(t)\) by differentiating \(\mathbf{v}(t)\).

3. Compute \( a_T \) and \( a_N \) using the appropriate formulas involving \(\mathbf{v}(t)\), \(\mathbf{a}(t)\), and unit tangent vectors.

This task requires knowledge of vector calculus and specifically the handling of vector functions and their derivatives.
