While on the moon, the Apollo astronauts enjoyed the effects of a gravity much smaller than that on Earth. If Neil Armstrong jumped up on the moon with an initial speed of 1.51 m/s to a height of 0.700 m, what amount of gravitational acceleration did he experience?

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.
