How do you solve this very hard riddle?

Question

Please tell me, thanks!

Answer 1

A B and C is... the bullet will pass out of the window. know why?

it's kinda hard to explain. it's sort of like why if your riding in the train and you throw a ball up in the air, and it doesn't fly back to the back of the train. the bullet will travel in it's regular speed no matter what speed the train is going. because the train isn't open, there's no wind resistance.

part two: don't shoot the gun...

Answer 2

That's relative velocity,

add the velocities in the first case. For the second case, all he needs to do is shoot a bit upwards or downwards. He cant get hit if the bullet is not in his plane...

Answer 3

the man would need to go to wal mart

buy world of warcraft

and waste his life away before dying

that should stop the bullet

Answer 4

it went bye bye.....i don't know!!is it math?i am not good at math!i tried i read atleast 2 times.i am guessing it went bye bye!!!bye bye we will miss u go kill someone bad will u?:'(

Answer 5

sayy what???

Answer 6

The train goes both ways, just like you! So when you are at the back of the train while it goes backward it shoots in the train. When you go to the front while going backwards you just shoot out the window.

Answer 7

Ah, the old relativity questions...It all depends on your vantage point..

A)  The bullet would appear to the man to disharge normally, moving away from the train at 3,600mph.  To the stationary observer, the bullet would move in the same direction as the train at a rate of 3,600 mph.

B)  The bullet would appear to the man to disharge normally, moving away from the train at 3,600mph.  To the stationary observer, the bullet would appear to just drop straight down to the ground.

C) A)  The bullet would appear to the man to disharge normally, moving away from the train at 3,600mph.  To the stationary observer, the bullet would move in the opposite direction as the train at a ground speed of 1,800 mph.

Part 2:  This is not a very practical question.  Unless the wind resistance affected the bullet differently than the train and the shooter, the bullet should travel away from the train at a rate of 3,600mph (to the observer, it would travel 3,600+trainspeed).  If the wind resistance was a factor, it would first knock the man down who was holding the gun before it would cause the train to catch up to the bullet.

Answer 8

I think i just got cramp in my brain lol

Answer 9

I think speed didnt matter in this case.the bullets get stuck to the trails.

Answer 10

The bullet always goes the same speed backward and forwards, its just the train moving that makes it appear differently.

Answer 11

head ache very sore head ache

Answer 12

math burns my brain...

Answer 13

i dont think that would work because of the magnetic bullets,good riddle by the way : P

Answer 14

thats confusing

Answer 15

it donesnt matter how fast the train is going, the bullet will still shoot. if it wasn't that way, then we would all fly back in a train, and couldnt walk forward if a bullet couldnt even go ahead
