Ever since I was a kid wanted to ask this if I suspend a car mid air and rev it up to 100mph then drop it how far would it go without me touching the gas or break not even once? (lemmy.world)

There's a lot of variables, so let me make some assumptions and you tell me what I'm getting wrong.

  1. Let's say it's maybe 30ft in the air.
  2. It's a car that will be able to withstand the impact as in not break apart and keep the motor running and tires spinning on first impact.
  3. It is dropped with 0 momentum, so there's no initial velocity until gravity applies.
  4. Tires are spinning at 100mph, keep spinning through the first impact and stop spinning when it's airborne again.
  5. The "how far" measures the distance between the first ground impact, and then the second ground impact after the bounce.
  6. Ground is your average road asphalt in dry weather.
  7. No slope, the ground is perfectly flat.
  8. The car is autonomous, so there's no forces from the driver affecting the calculation.

Alright I'm not nerd enough to do some example calculations but if these assumptions fit your idea, someone else can run with it.
