The andromeda galaxy is approaching our galaxy with a radial velocity of 120 km/s. given the galaxies present separation of 800 kpc, and neglecting both the transverse component of the velocity and the effect of gravity in accelerating the motion, estimate when the two galaxies will collide.
The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy that is 2.5 million light-years away from Earth and the closest big galaxy to the Milky Way. It has a diameter of roughly 46.56 kiloparsecs.
The Milky Way, which houses the Solar System and Earth, and the Andromeda Galaxy are anticipated to collide in roughly 4.5 billion years. This galactic collision will take place between the two largest galaxies in the Local Group. The Andromeda galaxy is the brightest galaxy outside of our solar system. It is the furthest object that the majority of us humans can see with our unaided eyes at a distance of 2.5 million light-years.

Answer:
A shorter than the original source and in the researcher's words
Explanation:
The summary is an abridged version of the original source and in the researcher's own very words.
Summaries gives an over-arching perspective and excludes implicit details from a given text.
A summary should not be detailed and must avoid overt illustrations. They must capture the true essence of piece leaving out flowery details.
A summary should be lesser in length than the original piece. Any third party reader should immediately be able to grab the details of the original piece from the summary.
i belive the answe is c and if im wrong im tarrably sorry
The work done by the friction force to stop the player is equal to his loss of kinetic energy:
The work done by the friction force is the magnitude of the force
times the distance covered by the player, d:
The loss in kinetic energy is simply equal to the initial kinetic energy of the player, since the final kinetic energy is zero (the player comes to rest):
Substituting into the first equation, we get:
from which we find d, the distance covered by the player:
I would google "Earth Science textbook free online" and see what you get.
Good luck!
Hope this helps~!
