how long would it take to fall to the centre of the earth?

Question

if you could fall to the centre of the earth how long do you think it would take??????????????

Answer 1

Terminal velocity is 32.6 ft per second

Answer 2

It is indeed a hypothetical question.
All the same we attempt to answer it.
ASSUMPTIONS
*we assume it is possible to fall up to the
center of Earth* radius=4000miles
*We remain unaffected by temp of the
order of 6500DegC
*the acceleration due to gravity will
start increasing enormously as we
approach the center. It will be nearly
infinite at the center
*let the average value of acceleration due
to gravity=g(av)
S=ut+1/2 g(av)T^2
u=o
T^2=4000*5280Ft*2/g(av)
T^2=42240000/g(av)
t=6499/sqrt g(av)
at surface g=32ft/sec^2
we take g(av)=100ft/sec^2
t=64.99sec
Calculation of g(av) is possible by plotting the curve
g(r)=GM/r^2 and evaluating the area to arrive at the average.At ground level its value is 32ft/sec^2 at the center this value shall be infinite since r=0

Answer 3

Forever, too much high density rock would stop you, assuming you could penetrate the low density sediments or water covering the extreme outside of the earth.

Answer 4

Well, that depends! It is all relative...Einstein knows that all too well. It could take 2 seconds or it could take forever.
