Does the Arrow Move?

Half way

Makes sense to me. The answer is 15 inches X 2.

Problem solved then! Whew! That was rough. Time for a nap.

The arrow does not wait for you to do your math.

It is quite capable of reaching an infinite number of 1/2 units in under a handful of seconds and once it has done so, it then plunges into its target with the joy only an inanimate object can feel at a job well done.

OK! The arrow gets a nap! Naps on the house!

Yawn

Actually the tip of the arrow never reaches the target for at the micro/nano level there is no tip and no target surface.

It's just a planck length meeting a planck length. (hypothetically, I think)

Very good, Tywvel. But now that you've destroyed the question by altering the scale of reality (from macro to micro), can't we still say that the nano bits making up what we are calling the arrow's tip can or will pass through and pass the nano bits making up the target surface?

Good point JLNobody, though I think the nano bits of each object do not reach or pierce each other, they merely share a common space.

If objects at the micro level are mostly empty space there is no boundary between them, and so no ?'them'. Our universe may be an arrow and a target from some perspective outside it. But that perspective is not available to us nano bits.
