The

x

- and

y

-coordinates of a particle moving in the

x

y

plane are

x=1-2t+t^2 \text{ and } y=4-4t+t^2.

For the given situation, match the following columns:

Column I	Column II
(a) $y$ -component of velocity when it crosses the $y$ -axis	(p) $+2\,\text{SI units}$
(b) $x$ -component of velocity when it crosses the $x$ -axis	(q) $-2\,\text{SI units}$
(c) Initial velocity of the particle	(r) $+4\,\text{SI units}$
(d) Initial acceleration of the particle	(s) None of the above
