How do astronomers think the moon was formed

the giant-impact hypothesis, sometimes called the big splash, or the theia impact suggests that the moon formed out of the debris left over from a collision between earth and an astronomical body the size of mars, approximately 4.5 billion years ago, in the hadean eon; about 20 to 100 million years after the solar   hope this < :

unbalanced force

explanation:

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
