Arock dropped on the moon will increase its speed from 0 m/s ( its starting speed when first dropped) to 4.9 m/s in about 3 seconds. what value do you calculate for the magnitude of the acceleration of gravity on the moon?

Acceleration, a = 1.64 m/s²

Explanation:

It is given that,

A rock is dropped on the moon, its initial velocity u = 0 m/s

Its speed increases from 0 to 4.9 m/s, v = 4.9 m/s

Time taken, t = 3 seconds

We have to find the magnitude of the acceleration due to gravity on the moon. The magnitude of acceleration is given by :

Acceleration, a = rate of change of velocity

a = 1.64 m/s²

So, the value of  acceleration of gravity on the moon is 1.64 m/s². Hence, this is the required solution.

it takes hundreds of years to become stable.

if you have another question lmk.
