1.5t of TNT certainly has enough energy to vaporize 1.5t of TNT. And, as they say, "then some".

2000 kg of aluminum costs, what, 1/4 billion joules to vaporize? I get 6.25 billion joules of impact energy, not trillion, but still plenty. I am corrected.

You can move a fair bit of material out of the way with that many joules. I guess you would start by vaporizing the 2t of Al plus another several tons of rock, and then dissipate the heat by lofting stuff out of the way as it expands, recycling the heat energy back to kinetic as it cools.

You're right. s/trillion/billion/. The key fact is that the two ton object had the impact of 1.5 tons of TNT. Thanks.
