Answer:
At the highest point from where the body falls.....The kinetic energy is zero but the potential energy is mgh
when the body is in middle of its path the kinetic energy is half mgh and potential energy is half mgh
and when the body finally reaches the ground then the kinetic energy is mgh and potential energy is zero
