A person throws a ball up into the air and the ball falls back towards Urth at which point was the kinetic energy Be the lowest

When the ball leaves the persons hand

At a point when the ball is still rising

When the ball is at its highest point
At a point before the ball hits the ground

The kinetic energy of the ball is lowest when the ball is at its highest point. At this point, the ball has stopped moving upwards and has not yet started moving downwards, resulting in the lowest kinetic energy.
