.just before the ball hits the ground how are it's speed and kinetic energy related

Answer 1

When a ball is about to hit the ground, its speed and kinetic energy are related in the following way:

The kinetic energy of an object is directly proportional to the square of its speed. This means that the kinetic energy increases exponentially as the speed of the ball increases. So, as the ball's speed just before hitting the ground increases, its kinetic energy also increases significantly.

In summary, the speed and kinetic energy of a ball just before it hits the ground are directly related, with the kinetic energy increasing significantly as the speed increases.
