if you could dig a hole from England to Australia and jumped in feet first would you come out feet first there

Question

you'd have a special suit to get through the earth's core

Answer 1

Let's say one could dig a hole from England to Australia through the center of the earth and provide a protective heat shield around the outside of the hole to prevent the lava, heat, and pressure from the center of the earth from collapsing the hole.

Then you jump into the hole.

Gravity would pull you toward the center of the earth and your falling speed would increase until you reached the center of the earth. Since at that time, you would be falling really fast you would continue to fall past the center of the earth, but your speed would be slowing down because gravity would be pulling you back to the center of the earth.

At the time you reached the opening in the hole in Australia, your speed would have slowed down enough to allow someone to grab your ankles and pull you out, and yes you would have to come out feet first. However, for this to happen, you must overcome air friction, which would slow your fall into the hole and slow you down as you were coming out the other side. So, the hole would have to be pumped free of any gas and you would have to wear a space suit.

Also if you bumped against the edge of the hole, that would slow you down too, so you would have to have little rocket thrusters in the space suit to steady you in the center of the hole all the way through. That means the hole would have to be pretty large.

All in all, yeah you would come out feet first, but you'd better write someone and make sure they will be there to pull you out or you would start falling again back to England, and you would be like an eternal motion machine and stuff till you starved to death or had to go to the bathroom.

Answer 2

You couldnt dig a hole through the earths core as the centre of the earth is molten. However, if you could, you wouldnt come out the other end because gravity pulls towards the core, so you'd be stuck there!

Answer 3

you're all lacking the element... You first could decide for who you may ask for permission to start the dig. counting on your ideals and what conspiracy theory is the style of the month, it has lots to do with who effectively owns the North Pole. This situation pales into insignificance as assuming you have permission to start digging, you may't purely pop your head/feet by the permafrost and the South Pole with out past permission from the South-pole financial administration League or SEAL. Assuming you get the final permissions then you definately could look for training from the professional Earth and Nocturnal training and Uniformed international Navigation team or PENGUIN – this might fairly actually be a distinctive kettle of fish altogether. while a majority of those purposes have been surpassed then you definately could exercising severe warning in the previous you may attitude the regular enterprise for Lateral administration family members Board of Earth Air and factors or unexpected loss of life as they in many situations manage on a widely used foundation. the respond isn't an elementary one by ability of any ability, we've heard of vaporisation and the ‘yo-yo’ consequence, a majority of those hurdles could be triumph over, which brings us to the coaching. have you ever taken section in a hurdle race underground? you may first evaluate training this suggests in the previous you even purchase a spade.

Answer 4

Yep.

Newton's laws of motion.

Gravity pulls you down, once you past the point where gravity drags you back up, you're momentum is such that you should almost reach the surface if not go past the surface.

You'd be falling at 10 feet per second squared and excape velocity is 8 feet per second squared.

Answer 5

If you dug a hole all the way to Australia from England you wouldn't need to jump in, because it would mean you having to go all the way back again to do so.

Answer 6

Yes. And then you would fall back through to the other end. In fact you would bob in and out of the hole as gravity stopped your fall and pulled you back.

Answer 7

yes

Answer 8

yup feet first for sure

Answer 9

no you are spinning clockwise half way then you will turn upside down turning anti clockwise

Answer 10

no, you stop in the middle cause of the gravtiy.
