Since the astronaut is in orbit, so is the shoe. Um, never?

If an astronaut is at 200k, either he is in orbit, or he is on some sort'a geosynchronous platform (such as a really big tower or attached to a cable going up to a satellite in a geosynchronous orbit.).
If he were on a geosychronous platform, it would take
t= (2d/a)^.5
= 200 secs
(Actually, it would take a little more because of centripetal acceleration, but not much)
But, if he were in orbit and he dropped his shoe there would be no acceleration since the centripetal forces would balance the gravitational forces and the shoe would just stay right there.

first the astronaut is in orbit so several things would happen, it would float around space
burn up before it even got close to the ground because of the atmosphere
and the astronaut would be dead
Happy homework

200 km = 200,000 m so 200000/10=20000 seconds...

200 kilometers = 200,000 meters.
200,000 divided by 10 = 20,000 seconds.
20,000 seconds = 333.333333 minutes.
333.3333333 divided by 60 minutes = 5.5 hours.

the shoe will burn up upon reentry, and if the astronaut is missing his shoe, he will be dead from his pressure being relieved from his space-suit

y would u ask? just do the math.ez w no air resistance. plus . . . here onearth, it's 9.8 m/s/s

depends - if they runnin shoes they'll get there faster

It wouldn't. It would burn up before it got here.
