<h2>Acceleration due to gravity in moon is 1.5 m/s²</h2>
Explanation:
We have equation of motion s = ut + 0.5 at²
Here the ball travels 3 m less distance in fifth second compared to third second.
That is
            s₃ = s₅ + 3
Now we have
Distance traveled in third second, s₃ = u x 3 - 0.5 x g x 3² -  u x 2 - 0.5 x g x 2²
            s₃ = u - 2.5 g
Also
Distance traveled in fifth second, s₅ = u x 5 - 0.5 x g x 5² -  u x 4 - 0.5 x g x 4²
            s₅ = u - 4.5 g     
That is
            u - 2.5 g = u - 4.5 g + 3
              2 g = 3
                 g = 1.5 m/s²
Acceleration due to gravity in moon = 1.5 m/s²
 
        
        
        
The answer is Monocline. And I checked it, it's correct.
