The best way is to stab it in the head. Like if you were fighting the grim reaper, stab it in the face. That's where you stab the Nazgul. They can't swim, either, so you could try to make them drown.

Read The Lord of the Rings by J.R.R. Tolkien. The Nazgul are fictional characters in that series of books.
The unofficial Lord of the Rings community online offers various pictures of the Nazgul via its website and on its wiki. You can also ask the community directly for more detailed information regarding the Nazgul.
The Nazgul King stabs Frodo once in the shoulder. The tip of the morgul knife used snaps off inside Frodo. The tip is poisoned, but cannot kill, it is intended to cause fading: making Frodo permanently invisible (like the ring does) but also the slave of the Nazgul King.
They are very hard to kill, but it is possible. Elrond uses one of the elven rings of power to sweep a group of Nazgul away with a deluge, destroying their physical bodies and sending their incorporeal essences fleeing back to Sauron. Sauron however was clearly able to return them to working order. In the third book, Eowyn and Merry together kill the Witch-king of Angmar, the lord of the Nazgul, the chief of the nine Ringwraiths, and this defeat is described as permanent.
The Witch King is the chief leader of the Nazgul (the Black Riders or Ringwraiths). The dragon he rides is called his fell beast. It has no specific name.

Nazgul do not fly. They are the shadows of men enslaved by Sauron through the use of the 'Nine Rings for Mortal Men doomed to die." They had flying steeds, fell beasts that they rode, it is supposed that these steeds flies fairly fast, particularly when they are in a hurry. In the movie, "The Return of the King" Gandalf says to Pippin that from Edoras to Minas Tirith is "three days ride, as the Nazgul flies... and you'd better hope we don't have one of those on our tail." In addition, it says at the very end of book 3 (about the middle of two towers) that a Nazgul can fly 200 leagues (about 800 miles) in "a few hours". Assuming "a few" means 3-5, a flying Nazgul in a hurry is moving somewhere between 160 and 270 Mph.
