When body is dropped from height, the potential energy deceases and kinetic energy increases. A ball dropped from height will conserve only kinetic energy.

A ball is dropped from a height of 10m. Ball is embedded in sand of 1m...
Explanation:
When the ball is dropped from a height of 10m, it gains potential energy due to its position above the ground. This potential energy is converted into kinetic energy as the ball falls.
When the ball hits the sand and comes to a stop, its kinetic energy is converted into other forms of energy, such as heat and sound. The ball loses all of its kinetic energy and does not bounce back up.
Conservation of Kinetic Energy:
Kinetic energy is the energy possessed by an object due to its motion. In this scenario, when the ball hits the sand and stops, its kinetic energy is completely transferred to other forms of energy. Therefore, the only energy that remains conserved is the initial potential energy of the ball.
Conservation of Momentum:
Momentum is the product of an object's mass and velocity. In this scenario, the ball has a certain momentum when it is dropped from a height of 10m. As the ball hits the sand and comes to a stop, its momentum decreases to zero because its velocity becomes zero. Therefore, momentum is not conserved in this situation.
Conclusion:
Based on the explanation above, the correct answer is option 'A', which states that only kinetic energy remains conserved. The ball loses all of its kinetic energy when it hits the sand and stops, and momentum is not conserved.
