If you are on a train that is traveling at 1000 mph going north,?

I assume you mean "as viewed by a stationary observer outside the train" - in which case, it will fall straight to the ground, a distance of maybe 1.5 meters.\n\nAnd dude, 1000 mph? That is one helluva fast train.

it depends how fast u go. lol

its 225 mph or 362 kmph

Hey, mammalboy. Get a clue. Trains are still used today but tracks don't run everywhere that roads go. Genius.

Let us assume that the speed of the train was x km/h and let us also assume that the length of the tuneel to be "d" km.\nNow the man has already travelled one-fourth of the tunnel.So he has two options open for him either to run back a distance of d/4 back to his entry-point or to run forward to cover a distance of 3d/4 miles.\nAgain, as the man has two options,the train may also come from two direction.So in one case the relative speed of the man and the train would be x-12 mph and in another case it would be x+12 mph and as x>12 (ioh! otherwise the man could have saved himself and we need not had to toil so hard for solving this problem),x+12 would be greatr than x-12\nNow we can say that the shorter distance traelled by the man was covered by less relative speed and the loner distance coverd by the greater measure of relative speed and as the man got knocked down just at the end of tunnel,the time taken was the same\nTherefore,(d/4)/(x-12) =(3d/4)/(x+12)\n1/(x-12)=3(x+12)\nBy solving the above equation,we get x=24 miles\nTherefore the speed of the train was 24 miles per hour.\nNow it may be noted that the ration of the distance the man ran \nand the ratio of the relative speed in two cases are the same It is\n1:3.So in eithr cases the train was at the mouth of the tunnel\n(You may ask how I solved the problem.Well I started my service-life as an enginer in the Railwys and used to look aftr railway track and yes u r right tunnels)\n\n.I

Impossible.\n\nVariance is Time. To get the average of 60 mph for 2 milels journey, you must know the time.\n2 miles/time= 60 mph\ntime = 2/60 *60 = 2 mins\nsince at 1st mile the train has traveled at 30mph. It has already spent 2 mins. So, it's not possible to get average of 60mph.

when you travel faster than the speed of sound.

About 1000 feet per sec.

Neither you, nor the train, could ever travel at the speed of light since both of you have some non-zero rest mass.\nIn order to accelerate something with a non-Zero rest mass, an infinite amount of energy would be required....and in the whole universe, there is not an infinite amount of energy.\n\nBut lets say you were traveling just under the speed of light...at 99.99999999999999% of c and you began to run toward the front of the train, \nyou would still NOT be traveling at or above the speed of light (as seen from an outside, "stationary" observer) since at relativistic speeds such as this, velocities do not add in the normal Galilean way, you would still be traveling slower than the speed of light.

a train runs at a speed of 10kmph and u chase it at a speed of 4 kmph , then the speed of the train will appear 10-4=6kmph to u.\n\nbut this is not the case with light rays. u chase it with any speed, its speed will always be 3*10^8 mps\n\nlong ago this boggled the scientists and they came up with relativity theory.\n\nconsider the example given above(train & u)\n\nspecial relativity: \nif both (train & u) r not changing your speeds again and  again then we use special relativity to compare motion between train & u.(ie both are non-accelerared frames)\n\ngeneral relativity\nif either-one/both (train & u) r changing your speeds again and  again then we use general relativity to compare motion between train & u.(ie either-one/both are accelerared frames)

stop the policeman giving you a ticket for speeding.\n\nI'm sure we will all find this useful.

Is that technology now being used?  I knew of European and Asian trains capable of 200+ mph speeds, but nothing in the supersonic range.  Rhetorically speaking, I suppose they would have no point.  If anything in this instance, the best way to imploy horns would be at actual crossings, which could be activated with plenty of time to warn pedestrians and automobiles before the train reached the location.

if it is speeding........3 years.

uh?  faster than your car.

Yes. The temperature drops 1 degree Fahrenheit for every 1000 feet you go up.

its a kilometer...1000 meters
