The table below gives $x$ and $y$ coordinates of a particle in the plane at time $t$.

Assuming that the particle moves smoothly and that the points given show all the major features of the motion, estimate the following quantities:

(a) The velocity vector and speed at time $t = 1$.
$\vec v(t) =$
speed =

(b) Any times when the particle is moving parallel to the $y$-axis.
times =
(Enter the times as a comma separated list, or enter none if there are none.)

Any times when the particle has come to a stop.
times =
(Enter the times as a comma separated list, or enter none if there are none.)
