Answer:
1.54 m/s²
Explanation:
The free-fall acceleration is calculated as
g = w²r
Where w is the angular velocity of the satellite and r is the radius of the moon.
The angular velocity can be calculated as
Where T is the period, so
T = 110 min = 110 x 60 s = 6600 s
Then,
Finally, the radius of the moon is r = 1.7 x 10⁶ m, so the free-fall acceleration is
Therefore, the answer is 1.54 m/s²
