Well the flaw in this line of reasoning is that Beethoven has stupidly misunderstood vectors. Look, if the velocity of an object is constant, it has no acceleration. But the velocity of this centipede is not constant! The speed is constant but its direction keeps changing. Again its important to distinguish between vectors and scalars. Velocity is a vector, it has a magnitude and a direction. You can't blame Beethoven for getting this wrong, he's quite busy decomposing.
