The horizontal acceleration i.e. Vx throughout the trajectory remains constant only of the air resistance is neglected. The gravity can affect the y-component of velocity but is unable to affect its...
Vertical means up or down, horizontal means left or right (or forward or backwards, but without changing the altitude).

There is no acceleration horizontally, only vertically due to gravity (g=9.81ms^-2)
It stopped....
