Your school subject is "school"?? Is there a textbook you've been assigned in the subject "school"? If so, I recommend you read it.

The maximum height is the point where the ball runs out of gas,
stops rising, starts falling, and it's velocity changes from upward
to downward. At that instant, it has no speed, so its kinetic energy
is zero.
