Do you know where you got this calculation from? I may try using it with this three mile tall character I know.WeeklyBattles said:Depends on what's surviving it but for a human surviving reentry it's Building level
@Ant Rereading and paying attention to this particular answer Lina made, I understood how this works.Lina Shields said:So depending on where said person in question is being dropped from, we can find two answers for this.
The minimum impact velocity varies depending on the size and the surface gravity (mass and density of said planet affects this) of the planet in question, but the kinetic energy here applies to planets w/similar size and gravity as Earth.
- KE (if person is being hurled from outer space) = 0.5*(mass of human)*(72000^2) = 2.592e11 Joules, or 61.95 Tons of TNT. City Block level+
