Two spherical asteroids have the same radius R. Asteroid 1 has mass M and asteroid 2 has mass 1.97·M. The two asteroids are released from rest with distance 13.63·R between their centers. What is the speed of second asteroid just before they collide? Give answer in units of (G·M/R)1/2.

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 arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
