Vertical velocity means that the sideways speed doesn't count at all, just the rate at which height is lost.

Think about what it is in the shape of the rail that makes vertical velocity increase or decrease at any point, and connect that with how increases or decreases of vertical velocity show up on the graph.

Here are the actual four curves. Can you matchthem with the graphs?
