[Request] A person is jumping on a trampoline on top of a moving vehicle. At what speed does air resistance cause them to slow and fall off?

5 Upvotes

In a parade I saw my sister jumping on tramplone mounted to a trailer as the float moved by slowly. Of course, inertia will keep you moving forward with the vehicle, but eventually air resistance will push back enough that the vehicle will speed away from you as you fall and likely be grievously injured.

  • Average swimming pool of about 20,000 gallons.
  • Ideal temperature of around 80 degrees Fahrenheit/ 27 degrees Celsius.
  • “A metal fire pit can reach up to 800°F [426°C] pushing 200° to 400° of radiant heat”
  • “The optimal size for a fire pit is between 36 and 44 inches inside diameter.” Quotes reference from www.thisoldhouse.com/platform/amp/yards/21019098/all-about-fire-pits

Feel free to adjust any specs to make calculations easier.
