When the stone reaches its highest point, earth's gravity ensures it has to come down.
The maximum height hmax that a ball reaches when thrown into the air is the highest point it reaches before falling back down.
The instantaneous speed of an object at its highest point when thrown straight up in the air is zero. At the highest point, the object has momentarily stopped moving upwards and is just about to start falling back down due to gravity.
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
The kinetic energy of the ball is at its maximum when it is initially thrown, as it has the highest speed at that point. The gravitational potential energy of the ball is at its maximum when the ball reaches its highest point in the throw, where its height above the ground is greatest.
At the highest point, the velocity of an object thrown vertically into the air is momentarily zero as it changes direction. This is the point where it transitions from going upward to downward.

The instantaneous speed of an object at its highest point when thrown straight up in the air is zero. At the highest point, the object has momentarily stopped moving upwards and is just about to start falling back down due to gravity.
At the highest point, the kinetic energy is least.

No, the acceleration at the highest point is never 0.
The highest point a rocket reaches during its flight is typically the apogee, which is the point of maximum altitude. This is the point where the rocket reaches its peak altitude before descending back to Earth.
At the highest point, the velocity of an object thrown vertically into the air is momentarily zero as it changes direction. This is the point where it transitions from going upward to downward.

A baseball in play reaches its lowest gravitational potential energy when it is at its highest point in the air, such as when it is at the top of its trajectory after being hit or thrown.
The speed of the ball decreases as it moves against gravity and eventually reaches 0 at its highest point before falling back down.
Potential and kinetic energy are equal in a system at the highest point of a vertical motion, such as when an object is thrown straight up in the air.
