If earth has a deep hole in the ground.....?

Question

If earth has a deep hole in the ground from america to china for example, what will happen in the middel if someone throw him self in it, will he go back or he will keep going to china?

Answer 1

Hi. In his thermal suit our brave friend will find himself slowing down on each pass. (I know, he would actually get hit by the rotating Earth.) When he finally stopped moving up and up he would be floating in a near zero gravity zone.

Answer 2

Think about it like this. If a person jumps in the hole in America, gravity will pull him towards the center of the Earth. However, he will keep going untill he reaches the other end of the hole. Then gravity will pull him back towards the center again. He will go a little past the center and be pulled back again. This person will keep going bouncing back and forth unitl the energy runs out. At this point he will be pulled in towards the center and stay there.

Answer 3

As he would fall through the hole, the force of gravity would decrease until he hit the center at which point there would be no gravity (not really, but it can be treated as zero gravity because earth's gravity is pulling equally in all directions). Gravity would then pull him back toward the center of the earth, but he would be moving so fast he would continue toward china. Eventually gravity would stop him and he would fall back toward the center. Again he would go past the center and back toward america. This would repeat until the air resistance stopped him. (It would be like a spring.)

Answer 4

Well, his falling speed would reach a terminal velocity of around 54 miles per second. He'd reach the other side going this speed, and pop out of the hole like a whack-a-mole toy. Since he's going faster than seven miles per second, he'd reach escape velocity, and likely he'd actually make it to the atmosphere before the gravitational pull slowed him down enough to prevent his going into orbit.

If the gravity did pull him back before he became another satellite, then by that time the earth would have moved and he'd smack into a new position, since the hole is no longer aligned with the person who popped out of it. That's likely to hurt a lot.

Answer 5

Since the earths gravity always pulls toward the center of the earth, this is where our friend would be trapped....................that is assuming he did not but to a cinder before he got there, which is exactly what would happen.

Hope this helps.

Answer 6

i think you would sort of go back and forth but end up resting in the center of the earth. or something. it would be interesting to knwo what a scientist would say about it

Answer 7

if this should ever happen that person would die

Answer 8

he will meet his end( he will die).
