Flying Fast on Dumbo

LOL! The difference for me is I can do math, but I'm just extremely lazy! All I do is math at my job.

I let Google do most of the math for me. Ask for the circumference formula, it not only tells you but let's you plug in the radius and spits out the answer. All the conversion in units done in the Google input box: "20.94 ft/sec in mph". Answer spit out.

What if your elephant is descending? Don't elephants in a dive or climb have a greater instant velocity than those simply maintaining their height?
Presumably the Vmax would be at the very end of the dive, because it's when the arms are fully down at the elephant's rotational diameter is at its greatest point, that is, assuming we're calculating velocity relative to the plane of the Earth.
Time for more math.

Also Disney made a movie all about it....

I teach in the high school I went to and yet it was this post that gave me a horrible flashback to high school.
(and - no, I do not teach math. I think there's something posted somewhere in the school saying I'm not allowed if I ever came back. Something about wanting the kids to learn the right answers...)

When the arm is all the way down, it's not a Vmax since the pivot point is above it.

For extra credit, how many degrees above the orbital equator does the car have to be for the sideways vector towards the center due to being tilted is cancelled out by the apparent centrifugal G-force outward such that a passenger feels no lateral sheer? Keep in mind that the pivot point is six feet from the center of the ride.

Uhhh.... 42.
