Some science questions

If I was in an air craft ejected and then some one fired a 100Kt kinetic impact weapon at the air craft, while I was still within a few hundred meters how dead would I be?

exactly how many M/S of accelration is one G of accelration?

[Dargos]

snip.........how dead would I be?
?

um.....semi-dead?

Plane go boom, the sonic boom from the slug may just about smash you to pieces letalone any thermal effects.

You'd be pretty dead.

very dead.

exactly how many M/S of accelration is one G of accelration?

on Earth, 9.81 m/s^2.

on Mars, aproximately a third of that value.

On Jupiter, you'll suffer an acceleration of about 100 m/s^2

Conclusion: don't visit Jupiter.

so what would be about the maxium yield that someone could survive within a few hundred meters? (say 300)

I think you're confusing local gravity with the G constant. Because G is a constant, right?

What weighs more, a pound of feathers or a pound of sand

G is the universal gravitional constant, equal to 6,67259E-11. Newton/m^2 kg^2. It's not what we call g, which is the gravitic acceleration suffered by a body on Earth's surface, equal to 9.8 m/s^2.

He asked how much was g (at least, that's what makes sense, G is not an acceleration).

After answering, I generalized for the other planets.

BTW, g = G*m/r^2, where m is the planet mass and r the radius.

Not necessarily very dead. 100 KT of energy is far more than would be needed to destroy the plane, most of it would just keep right on going. If you're ejection seat got out out of the projectile's path, you might well survive.

exactly how many M/S of accelration is one G of accelration?

One G is about 9.8 meters per second per second (9.8 m/s^2).

Upon reading Valdemar's post, I suppose that if the projectile that hit the plane is supersonic, the shockwave probably would kill you.
