Question about flight, motion and physics

[Jaron]

Hi all,

I have a question for you guys..I'm no physics guy by any means so hopefully someone here can answer these questions:

1) When someone or something is ejected from a moving object, will their velocity at least initially match the object they were ejected from?

example: someone thrown from a car going 65 mph, or a skydiver jumping out of an airplane going 550 mph

2) If two objects are flying parallel to one another by a Z coordinate (aka one right above the other) at the same rate of speed, could a PERSON jump from the upper object to the lower object without the higher object having any kind of lead in distance?

example: Two airplanes  - one flying 30 feet above the other at the same rate of speed - could I jump out of the top airplane and land on top of the bottom airplane or would I begin to lose speed once I jumped out of the plane and completely miss?

All the theories that can be posted on Languish are no substitute for real world experimentation.

Trust me. This is going to a very good cause.

1) yes

2) the top plane better be ahead of the bottom plane.  Your body has more drag than a plane and no thrust.

Depending on the situation and the company, my body has plenty of thrust.

And the diet.

The amount of drag and resuling friction at 550mph would, I expect, be completely unsustainable for a human being outside of an aircraft, yes.  Even skydivers in a straight dive only get up to about 200mph and afaik that's already pretty bad.

I don't know if the exact stunt has ever been performed by wing walkers or other daredevils, but a 65mph transfer from one vehicle to another might be possible.

You never said you dropped your girlfriend from a plane.

In a vacuum, it would be easy to jump from one plane to the other.  Then again, in a vacuum, planes wouldn't be able to fly, nor would you be able to stay alive, for that matter.

[The Brain]

Vacuums are typically too small for planes or Jaron.

[Ideologue]

Untrue.  You can survive unprotected in a vacuum for a period, if you observe certain requirements (namely exhaling first, so that your lungs aren't fatally damaged from the lack of pressure).
