What is Horizontal Projectile Motion?

Horizontal Projectile Motion Suppose a body is thrown horizontally from point $\mathrm{O}$, with velocity $\mathrm{u}$. Height of $\mathrm{O}$ from ground $=\mathrm{H}$. Let $X$-axis be along horizontal and $Y$-axis be vertically downwards and origin $O$ is at point of projection as shown in fig. Let the particle be at $P$ at a time $t$. The coordinates of $P$ are $(x, y)$. Distance traveled along X-axis at time t with uniform velocity i.e. velocity of projection and without acceleration. i.e. v...
