You are completely wrong there, the important thing is the total relative 
speed between projectile and target. If the vertical component only matters 
you imply that the meteorite continues to move sideways with the same speed 
as before the impact (several kilometers per second). It does not. It stops 
dead and the kinetic energy is converted into heat and deformation.

Why? The _entire_ velocity is annihilated. The _entire_ kinetic energy is
converted to heat, which then produces the explosion that makes the crater
and blows the ejecta all over the globe."

Isn't this a new and unique interpretation of physical concepts? :-)

My answer:

Collision types

1. Elastic: The difference of the sum of the kinetic energy of objects
before and after the collision is zero.

2. Inelastic: A part of the sum of the kinetic energy converts to other
form of energy during the collision. 
2.1. Perfect inelastic: Velocities of objects are equal after the collision
therefore objects are moving together.

You have it that this is happened when an extraterrestrial object collided
with Earth.

What is the proof? Why didn't fly away a part or the whole object with less
velocity? And if the whole object stopped on Earth what flown to the
atmosphere and over the atmosphere? And from what got energy for the flying
if isn't from the kinetic energy of the object?
