square of velocity. But, yes, not linear.

Bingo, I re-read my email and when I said it goes up significantly
above 45, I omitted the fact (that you allude to) is that it goes up
as the cube of velocity.

I encounter this square/cube controversy semi-regularly. Let me make a feeble attempt at illumination. Energy lost to wind drag does go up with the cube of the speed. That energy lost is per unit time and does not account for extra distance traveled at higher speed. On the basis of energy lost per unit distance traveled, the loss goes up with the square of the speed.

Clear? As mud?
