Kinetic energy on reaching ground=o
As at ground the velocity becomes zero
In my point of view zero
Hoping this may help you

mass=200g
height=2m
Potential energy =mgh=200*9.8*2=392J
Potential energy at highest point=Kinetic energy just before hitting the ground
so, kinetic energy=392J
clappping bro
its wrong
you took mass in gram and did not changed in kg
so how ans can come in joule ??
answer will be 4 j
yeah thats a mistake but anyway thank u for giving bro.............
