Look up a video of one. Assuming a revolution takes 2π seconds, the speed in m/s is the same as the radius in meters, which is around 5. Multiply by 3.6 to convert into 18 km/h, which seems realistic for the milder ones. The apparent horizontal centrifugal acceleration will then be 𝑣²/𝑟 = 5 ms⁻² ≈ 0.5𝑔, which corresponds to an angle of approx. 26° from the verical, reasonably close to the video.

I’d let them math all over me anytime 👌😩🧮

How does one sound in π • seconds?

It’s about 6.5 seconds in the video. I rounded that to 2𝜋 so I could do the math in my head (other than the tan⁻¹(0.5), of course)
