Answer:
12.3 s
Step-by-step explanation:
The acceleration due to gravity on the moon is
where g (9.8 m/s²) is the acceleration due to gravity on the Earth.
Distance to the ground, s = 120 m
Initial velocity = 0
Use the second equation of motion:
s = u t + 0.5 gt²
⇒ 120.0 m = 0 + 0.5 (1.63 m/s²) t²

Thus, it will take more time for a bottle to fall on the Moon than on the Earth off the same height.
