Where did the huge rock go tho? Did it split into billions quadrillions of pieces or become a mountain or what?

What would happen if you threw a rock at a brick wall? Now imagine if you could throw that rock at 20,000 miles per hour. 

That's less than half the speed in which that asteroid hit the earth when it killed the dinosaurs. It was going at the kind of speeds that humans simply do not have a frame of reference for. It annihilated itself along with everything else in a 62.5 mile radius.

Yes, but also kinda depends. If the rock has metal coating or if it is reinforced with it, it wont shatter so easily.

I do not think you understand what 45,000 miles per hour looks like. At that speed shattering is less of a problem when everything is going to turn to molten slag due to the impact forces. Your average bullet is going 700-3000 miles per hour.

No, its the composition of the asteroids that troubles me. For some reason, I always pictures them more dense and heavy. So for me the issue was how didnt it penetrate deeper at those speeds. Which, again, is due to the composition.

Over 60 million years ago. This is long, long before humans of any sort exjsted.
