At what point in a projectile’s trajectory does it experience a minimum velocity?

Minimum velocity occurs at the top of the trajectory, where
the projectile stops rising and starts falling.  For a split second,
it has no vertical speed at all, and its velocity is only the horizontal
speed (which doesn't change).

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
