Question

Calculate the acceleration due to gravity on the moon . the feather and hammer were dropped from a height of 1.2 m and took 1.22 seconds to fall .

Answer 1

1.61 m/s²

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.
