Starting from the origin at time $\mathrm { t } = 0$, with initial velocity $5 \widehat { \mathrm { j } } \mathrm { ms } ^ { - 1 }$, a particle moves in the $x - y$ plane with a constant acceleration of $( 10 \widehat { \mathrm { i } } + 4 \widehat { \mathrm { j } } ) \mathrm { ms } ^ { - 2 }$. At time t , its coordinates are $\left( 20 \mathrm {~m} , \mathrm { y } _ { 0 } \mathrm {~m} \right)$. The values of t and $\mathrm { y } _ { 0 }$ 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
