Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. Stars start their lives as clouds of dust and gas.
Answer:
U=α/(x+x_0)^2
v=1.88m/s
Explanation:
We have that
(a)
The potential is calculated by using
(b)
m=0.5kg
The acceleration can be obtained if we calculate the force for x=4, and after we compute the acceleration
and finally, we can use the equation for the final speed
I hope this is useful for you

Two objects allowed to move freely will accelerate toward each other
in response to the gravitational forces between them.
It doesn't matter whether they have equal masses or vastly different
masses ... each object accelerates toward the other one.
The less-massive object has greater acceleration, and the more-massive
object has smaller acceleration.
Yes. When you fall to the Earth, the Earth falls to you, but with less
acceleration because it has less mass than you have.
