A particle is moving in \( x y \)-plane with \( y=x / 2 \) and \( v_{x}=4-2 t \). Choose the correct options.
\( \mathrm{P} \)
(1) Initial velocities in \( x \) and \( y \) directions are negative.
W
(2) Initial velocities in \( x \) and \( y \) directions are positive.
(3) Motion is first retarded, then accelerated.
(4) Motion is first accelerated, then retarded.
