Could a submarine survive an asteroid impact?

Depending how fast the asteroid would travel. As soon as I'm home I'll do the calculation

>>8688789
In such an event you have higher chances to survive in a 100m underground shelter than 2km deep undersea.

>>8688789
It depends

Can anyone who isn't stupid about this kind of thing tell me that I'm right when explosions are worse in water?

Shock waves behave differently with different materials. That is because they are non-linear processes which heavily rely on density and the bulk modulus of a material.
I will keep it short here:
You can think of the bulk modulus (B) as the spring constant of a material. The higher it is, the more difficult it is to compress. Water and solids have a bulk modulus and so they are said to be uncompressible.
B is also proportional to the speed of sound in a medium.

>Now back to explosions
Explosions are basically shock waves. They are expansion followed by compression, a cycle, and then again. In air, because of its small B, only one cycle appears and they also do not propagate too much.
But underwater, then it is the opposite. There is usually separate cycles, all of which travel at really heavy speed. These subsequent series of compression and expansion creates fractures and breaks a lot of materials. That is why depth charges are so dangerous.

>What about the original problem?
An asteroid hitting the ocean would create an enormous shock wave travelling at high speed. This wave would implode the submarine instantly.

I'd want to be in another ocean, separated by one damn big continent.
It might not be an extinction level event, but I imagine a lot of people would be inconvenienced by it.

>>8688871
It doesn't though. You just need to use the terminal velocity for a 1km diameter sphere.

>>8689629
You're forgetting that the shockwave loses energy at a rate proportional to the inverse square of the distance.

>>8689688
I know but there is still enough energy to destroy the submarine.

>>8689713
Show me the math then.

Do it yourself, I have a job to do.
