The position in the graph between 4 - 6 seconds is the region of constant velocity.
<h3>What is constant velocity?</h3>The term constant velocity refers to the period in the graph when the velocity is not changing with time. As such, the graph is shown to be a flat portion at such a point.
Hence, it follows that the position in the graph between 4 - 6 seconds is the region of constant velocity.

Answer:
Explanation:
We can prove that this is a circular motion if we demonstrate that the norm of the vector is independent of time. Hence we have
but cos^2(3t)+sin^2(3t)=1. Thus we obtain
The norm is independent of t, thus, the particle describes a circular motion
