If you want the graph to show the acceleration of the ball against time,
then the graph is a horizontal line.
If you want the graph to show the velocity of the ball against time,
then the graph is a straight line sloping downward.
If you want the graph to show the height of the ball against time,
then the graph is a parabola that opens downward.
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 downward acceleration of a thrown object in projectile motion is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration acts vertically downward and affects the vertical motion of the object while the horizontal motion remains unaffected.
The speed decreases when an object is thrown vertically up because of the force of gravity acting against the object's upward motion. As the object goes higher, the force of gravity slows it down until the object reaches its maximum height, where its speed momentarily becomes zero before accelerating back downward.
The speed of the body at the highest point is 0 m/s. The acceleration acting on the body is the acceleration due to gravity (-9.81 m/s^2), which acts downward throughout the motion.
The ball is affected by the force of the earth's gravity.

Ignoring air resistance and using g = 9.81 ms-2, velocity = 20.38 ms-1.
The ball is affected by the force of the earth's gravity.
The highest point is the point where the ball's velocity transitions from upward to downward. At that instant, the ball's speed, velocity, momentum, and kinetic energy are all exactly zero.
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!
A ball thrown straight will curve downward due to the pull of gravity acting on it. As the ball moves forward, gravity exerts a downward force on it, causing it to follow a curved path towards the ground. This downward curve is influenced by factors such as air resistance and the initial velocity and angle at which the ball was thrown.
The acceleration of the ball just before it hits the ground is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 downward.
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
The thrown ball will (usually) have the highest velocity as the acceleration (resultant of force) used to throw it exceeds that of the other two balls. The ball thrown upward will have a higher downward velocity than the dropped ball even though their accelerations (due to gravity) are the same, as it has more time to travel downward. Although, If the ball thrown upward is thrown high enough, it may even travel faster than the ball thrown downward if the downward throw's force is not enough to beat the ball's terminal velocity (quite a bit of height would be required though).
