Starting from the origin at time $t = 0$, with initial velocity $5\hat{j}$ ms$^{-1}$, a particle moves in the $x$-$y$ plane with a constant acceleration of $(10\hat{i} + 4\hat{j})$ ms$^{-2}$. At time $t$, its coordinates are $(20\text{ m}, y_0\text{ m})$. The values of $t$ and $y_0$ are, respectively:
(1) 2 s and 18 m
(2) 4 s and 52 m
(3) 2 s and 24 m
(4) 5 s and 25 m
