$(A)$ $a_x=1 ms ^{-2}$ implies that when the particle is at the origin, $a_y=1 ms ^{-2}$
$(B)$ $a_x=0$ implies $a_y=1 ms ^{-2}$ at all times
$(C)$ at $t=0$, the particle's velocity points in the $x$-direction
$(D)$ $a_x=0$ implies that at $t=1 s$, the angle between the particle's velocity and the $x$ axis is $45^{\circ}$
