I used to do some parachuting. The average speed of a human in free fall is 220 km/h. the edge of space is 50 miles (75 km). Therefore, at 220 km/h, you would be free-falling for 20 minutes and 27 seconds before you splat on the ground. You wouldn't burn up in space because we don't have enough mass / speed to create enough friction to burn up. But you would probably black out from the lack of oxygen ;)

That's difficult because you would start falling, then reach a terminal velocity due to air resistance. However, your terminal velocity would change depending on how dense the air was. Air density changes depending on how high above the earth you are.
In the begining you would fall fast, because there would be nothing to slow you down. But the air would get thicker, slowing you more and more. You would probably heat up (your extra speed would turn to heat).
The bottom line is you would need lots of data and calculus to figure that out, so don't believe anyone unless they give you a reliable source.

it cant happen and how in the world can you calculate something when we dont know if there even is an edge to space, you may wanna know but you had better ask stephen hawking, hes the closest to figuring that out , and i honestly doubt he has time for your foolishness.

If you were at 'the edge of space', you would be free from the gravitational pull of the Earth.

first of all if u r out of earth orbit - the gravitational force is ZERO
ok?? but when u enter in the earth gravity u will accelareted to the earth and that can be calculated by PE=KE
PE=potential energy KE=kinetic enrgy

About 10 seconds. You would burn up in the atmosphere.

Several minutes! Long enough to pray for forgiveness.

that depends on how much surface area you have. you'd have to be pretty big to not burn up before you hit the ground.

To which "the ground" might you be referring?

^^^^no you wouldn't that's only when you were going super fast to orbit the earth. it's probably in excess of an hour.
