A particle starts from origin at `t= 0` with a velocity `5.0 hati ms^(-1)` and moves in `xy`-plane under action of force which produces a constant acceleration of `(3.0 hati + 2.0 hatj) ms^(-2)`. What is the `y`-coordinate of the particle at the instant, if `x`-coordinate is `84 m`?
Options:
(a) `36 m`
(b) `24 m`
(c) `39 m`
(d) `18 m`
