Thank you for your comments in your previous thread, I glad you found my explanation clear.
But even with a clear explanation, folks often find it difficult to know whether to use momentum or energy in questions when they are starting out in dynamics.

So let us work through this one., a step at a time.

I am going to assume the bullet is fired horizontally into the block as it would penetrate the same distance both in the vise and on the table, if fired vertically.

So when it is fired into the block in the vise;

What happens to the bullet and to the block?

Is energy conserved?

Is momentum conserved?

And the same questions for the shot into the block on the table,

What happens to the bullet and to the block?

Is energy conserved?

Is momentum conserved?
