Hiii Friend
We know that Potential Energy is equal to
m×g×h
now from here we have in question mass =50kg. P.E =1200 joule h ?
on putting value
1200=50×10×h
=> h=1200/500
=>h=2.4m
Hope It will help You
Have nice day my friend

Answer:
P.E=1200J
Mass of the boy =50kg
let the height be h
=》P.E=mg
we get
h=PE/Mg
h=1200/50×10
h=2.4m
