Question

An astronaut standing on the surface of the moon (mass = m, radius = r) holds a feather (mass = m) in one hand and a hammer (mass = 100m) in the other hand, both at the same height above the surface. If he releases them simultaneously, what is the acceleration of the hammer?

Answer 1

Explanation:

both hammer & feather will fall on moon surface with acceleration due to gravity of 9.81/6 m/s^2, since there is no atmosphere on moon, there will be no any air resistance.
