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.
