Final answer:
The object takes about 4 seconds to reach the surface of Earth from a height of 100m.
Explanation:
Acceleration due to gravity on the Moon is 1.6 m/s² or about 16% of the value of g on Earth.
To calculate how long it takes for an object to reach the surface of Earth from a height of 100m, you can use the formula t = sqrt(2h/g), where h is the height (100m) and g is the acceleration due to gravity on Earth (9.8 m/s²).
Substitute the values into the formula: t = sqrt(2*100/9.8) ≈ 4 seconds. Therefore, it takes approximately 4 seconds for the object to reach the surface of Earth.
