This can be solved using momentum balance, since momentum is conserved, the momentum at point 1 is equal to the momentum of point 2. momentum = mass x velocity
m1v1 = m2v2
(0.03kg x 900 m/s ) = 320(v2)
v2 = 27 / 320
v2 = 0.084 m/s is the speed of the astronaut
Answer:
Explanation:
Let us first calculate for Virgo

Using Hubble's law
For Virgo

Percentage difference for the Virgo

Now for calculate for Corona Borealis

Using Hubble's law
For Corona Borealis

Percentage difference for the Virgo

So clearly Hubble's law is more accurate for the closer objects
