Q4. The co-ordinates of a particle moving in $x - y$ plane are given by : $x = 2 + 4 \mathrm { t } , y = 3 \mathrm { t } + 8 \mathrm { t } ^ { 2 }$. The motion of the particle is :\\
(1) uniformly accelerated having motion along a\\
(2) uniform motion along a straight line. parabolic path.\\
(3) uniformly accelerated having motion along a\\
(4) non-uniformly accelerated. straight line.
