Worked Solution

Step 1: On Earth, air resistance slows down light objects like feathers more than heavy ones. Step 2: The Moon has no atmosphere (no air). Step 3: Without air resistance, gravity pulls all objects down with the same acceleration regardless of mass. Step 4: They hit at the same time.

Correct answer: There is no air resistance to slow down the feather.
