![The position vector \( \mathbf{r} \) describes the path of an object moving in the \( xy \)-plane.
**Position Vector:**
\( \mathbf{r}(t) = 6 \cos t \, \mathbf{i} + 6 \sin t \, \mathbf{j} \)
**Point:**
\(\left( 3\sqrt{2}, 3\sqrt{2} \right)\)
**(a)** Find the velocity vector \( \mathbf{v}(t) \), speed \( s(t) \), and acceleration vector \( \mathbf{a}(t) \) of the object.
\( \mathbf{v}(t) = \) [Textbox]
\( s(t) = \) [Textbox]
\( \mathbf{a}(t) = \) [Textbox]
**(b)** Evaluate the velocity vector and acceleration vector of the object at the given point.
\( \mathbf{v}\left( \frac{\pi}{4} \right) = \) [Textbox]
\( \mathbf{a}\left( \frac{\pi}{4} \right) = \) [Textbox]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F18936370-e2cc-46bd-a4d0-3c2ee0736afc%2F3746b53b-ea28-4010-9fd3-cd321ac22173%2Fbeqt6kr_processed.png&w=3840&q=75)
