“I don’t think that is correct.”
At twice the speed, your “hitting surface,” the front of the train, goes through twice the volume of space. If the random flying objects are distributed evenly in space, then you have twice the chance of hitting one.
It is simple math.
No it isn’t. You go through twice as much space, but for only half as long. You’re oversimplifying and non simple problem. You also don’t know the direction of travel of the object.
” If the random flying objects are distributed evenly in space...”
And if they aren’t?
