A particle starts from origin at \( t=0 \) with a velocity
\( \mathrm{P} \)
\( 5 \hat{i} \mathrm{~ms}^{-1} \) and moves in \( x-y \) plane under the action of a
W
force which produces a constant acceleration of \( 3 \hat{i}+2 \hat{j} \mathrm{~m} \mathrm{~s}^{-2} \). The \( y \)-coordinate of the particle at the instant when its \( x \)-coordinate is \( 84 \mathrm{~m} \) is
(1) \( 12 \mathrm{~m} \)
(2) \( 24 \mathrm{~m} \)
(3) \( 36 \mathrm{~m} \)
(4) \( 48 \mathrm{~m} \)
