Answer:
The gravitational acceleration experienced was of 1.63m/s².
Explanation:
We know, from the kinematics equations of vertical motion that:

Solving for g, we get:

Since the final speed is zero, because Neil Armstrong came to a stop in his maximum height, we obtain:

Finally, we plug in the given values of the initial speed and the maximum height:

This means that the gravitational acceleration experienced by Neil Armstrong in the moon, was of 1.63m/s².
