Answer:
1.61 m/s²
Step-by-step explanation:
You want the acceleration due to gravity on the moon if an object dropped from a height of 1.2 m takes 1.22 seconds to fall.
Acceleration
The relation between time, distance, and uniform acceleration from rest is given by the formula ...
a = 2d/t²
For the given distance and time, the acceleration is ...
a = 2(1.2 m)/(1.22 s)² ≈ 1.61 m/s²
Acceleration due to gravity on the moon is approximately 1.61 m/s².
