Say a small 2 to 3 mile wide asteroid impacted the Pacific ocean near Zealandia. Mostly Iron going around 50,000 mph. Would the impact be great enough to force the submerged continent to rise above sea level? If that wouldn't do it, would any impact increase the mantle pressure enough to force that continent back above the waves? I know it was thinned by stretching and that caused it to fall below the water. Is there even enough rock left to raise it the 300 to 400 ft it would need to be raised?

3 mile Wide...at 50,000mph.

Sounds like an Extinction Level Impact.

I wonder how many of Us would survive to find out what happens after it strikes.

Ps - Someone else might be able to foresee & provide calculative Predictions, I can't.

You might have more luck raising a continent if the impact is from the other side. Supposedly there were major tectonic disturbances in the Indian subcontinent caused by the impact that created the Chicxulub crater.

(can you give me at least a week's notice before you try? I might have some things to take care of first...)
