So we see at the top most point the velocity the boy is zero and the earths pull is acting downwards
Given     
⇒ 
so using
v² = u² - 2gs
where g = acceleration due to gravity
s = total height
so 
0 = u² - 2gs  
⇒ s = 
⇒ 2 = 
putting
⇒  2 = 
⇒12 = 
so the boy can jump a height of 12 m on moon's surface
