Question

Astronomers believe the moon used to be much closer to the earth(mass= 5.98 x 10^24 kg). When it was at 1.92 x 10^8 m, half its current distance, what was its orbital seed?

Answer 1

1,442

Step-by-step explanation:

Correct for Acellus

Answer 2

V = √Me*G/d = √5.98*10^24*6.674*10^-11/(1.92^10^8) = 1,442 m/sec = 5,190 km/h
