The increase in the average kinetic energy of the ball causes the increase in the temperature of the ball.
Kinetic energy of a particle is directly proportional to its temperature.
A ball initially at rest acquires kinetic energy when an external force is applied to it. As the person strikes the ball with a bat, the ball gains momentum which increases its kinetic energy of the ball.
Temperature on the other hand, is the measure of the average kinetic energy of a particle. Consequently, as the kinetic energy of the ball increases, the temperature of the ball increases as well.
Thus, we can conclude that the increase in the average kinetic energy of the ball causes the increase in the temperature of the ball.

Answer:
Vertical height of the hill, h = 20.4 meters
Explanation:
Given that,
Speed of the bicyclist, v = 20 m/s
To find,
The vertical height of the hill.
Solution,
Let h is the height of the hill. When he approaches the bottom of the hill, the loss in kinetic energy is equal to the gain in potential energy. Using the conservation of energy as,
h = 20.4 meters
Therefore, the vertical height of the hill is 20.4 meters. Hence, this is the required solution.
