Question

Starting from the origin at time t = 0, with initial velocity 5$\widehat j$ ms^-1 , a particle moves in the x-y plane with a constant acceleration of $\left( {10\widehat i + 4\widehat j} \right)$ ms^-2. At time t, its coordinates are (20 m, y₀ m). The values of t and y₀ are, respectively:

5s and 25 m

2s and 18 m

2s and 24 m
