Lf a dropped hammer's velocity increases from 0.Omis to 15.0 m/s in 4.04s while on the moon, what is the acceleration due to the gravitational force
on the surface of the moon (m/s2)?

The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s2, about 16.6% that on Earth's surface or 0.166 ɡ.

Heres your answer.
