I mean it’s alaska so i’m assuming B but i could be very wrong
Answer:

Explanation:
We are given that
Mass of one asteroid 1,
Mass of asteroid 2,
Initial distance between their centers,d=13.63 R
Radius of each asteroid=R
d'=R+R=2R
Initial velocity of both asteroids

We have to find the speed of second asteroid just before they collide.
According to law of conservation of momentum




According to law of conservation of energy







Hence, the speed of second asteroid =
The answer would defiantly be option D "Nicolaus Copernicus." Copernicus was first to purpose the model of the universe, back in 1543 he presented a heliocentric model of the universe, he also made a geocentric model.
Hope this helps!
