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
