A ball is dropped from the top of a building. When does the ball have the most kinetic energy? as it is released just before it hits the ground half way through the fall after it has hit the ground

Answer:

as it is released just before it hits the ground

Explanation:

By conservation of energy principle  the total energy of a closed system is conserved.

At the release of the ball it has no kinetic energy (K.E). but has maximum potential energy (P.E.)

As ball just before hitting the ground it has no P.P.So alll energy has to converted to K.E. So maximum K.E. will be found as just before it hits the ground.

The ball will have most kinetic energy as it is released just before it hits the ground.

What is kinetic energy?

Kinetic energy is a type of mechanical energy acquired by an object due to its motion.

K.E = ¹/₂mv²

Velocity of a projectile

The velocity of an object decreases as the object moves upwards and becomes zero at the maximum height. Also the velocity of the object increases as the object moves downwards and becomes maximum before the object hits the ground.

Thus, the ball will have most kinetic energy as it is released just before it hits the ground.
