The terminal velocity in your model depends on both the height (via the relationship between height and total resistance) and also on the coil size (via $\Phi$, as discussed in the other answer). That's not the same thing as being "independent of the height." We can have some back-and-forth in the chat room for this question if you'd like. | |

Therefore, given any height, we can achieve any rate of acceleration we like, and therefore, any final velocity we like. Therefore, the velocity is independent of the height. | |
