Question about flight, motion and physics

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?

:P 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. :perv:

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.

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.

Vacuums are typically too small for planes or Jaron.

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).
