Problem

x

and

y

-coordinates of a particle moving in

x

y

plane are,

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

For the given situation match the following two columns :

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