If there was a tunnel from uk to Oz, would you get there quicker by plane or by freefalling down tunnel.?

Question

A 747 goes over 600mph, i'm pretty sure you wouldn't fall that quickly, but the route would be more direct.

Answer 1

By plane. 600 miles per hour in the 747 would get you the 12,000 miles or so (half circumference of the Earth) in 20 hours.

Falling straight through the Earth would be at a maximum velocity of 70 meters per second, or roughly 150 miles per hour (this is generous) and only account for air friction or drag . The linear journey of a little less than 8000 miles would take over 50 hours.

Answer 2

distance by plane is half circumfrence of the earth, or about 12,000 miles, or 20 hours
most human bodies reach critical velocity (speed limited by air drag) at about 120mph. distance through the earth is roughly 8000miles, or 66 hours.
to add a little bit of realism (but not too much), if you fall you accelerate due to gravity, but are limited at the critical velocity. then when you pass the center of the earth you are slowed by gravity. but because you're speed was limited by drag, you don't have nearly enough speed to reach the surface on the other side. you slow down long before you reach the surface and begin to fall back towards the center of the earth again. so you would never make it through.
take the plane.

Answer 3

Your speed will reach 8km/s in the center.

Travel time through the tunnel:
42 minutes regardless of wheater your
distination is Oz or Paris just across the Channel.


Lane: air drag ain't freefalling

Answer 4

Um...the only Oz I know of is over the rainbow. So falling thru a tunnel wouldn't get you there.

Answer 5

Free falling, if you were to take a plane you will have to figure in baggage claim, the ticket counter, the take off and etc....
