An astronaut drops a feather from 1.2 m above the surface of the moon. If the acceleration of
gravity on the moon is 1.62 m/s2 downward,
how long does it take the feather to hit the
moon's surface?

It take "1.49 sec" to hit the moon's surface. A further explanation is provided below.

According to the question,

Height,

Acceleration of gravity,

Initial velocity,

With the help of the equation,

→

By substituting the values, we get

→    

→    

→    

Thus the above answer is right.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
