Answer:
The correct answer to this question is Neither kinetic energy nor momentum is conserved.
Explanation:
Given - A ball is dropped from a height of 10m a ball is embedded in sand 1 m and stops.
To Find - Write about a ball dropped from a height of 10m a ball is embedded in sand 1 m and stops.
Neither kinetic energy nor momentum is conserved if a ball is dropped from a height and subsequently lodged in sand and stops.
The ball's weight and sand resistance are external forces. As a result, when there is no external force, momentum is not conserved.
Furthermore, because the ball will be under-accelerated and subsequently de-accelerated, the kinetic energy will not be preserved.
The ball's velocity will change as a result of the motion, and the kinetic energy will change as well. It will be zero at the rim, maximum at the sand surface, and zero once more at one meter below the sand surface.
