c. What happens to the kinetic energy of a ball when it hits the water? (1 point)
• Overall, kinetic energy is lost.
• Some of the energy is transferred to the water.
• Overall, kinetic energy is gained.
• All of the kinetic energy is kept by the ball.
b. Some of the energy is transferred to the water.
The correct answer is: Some of the energy is transferred to the water.
To answer this question, we need to understand the concept of kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. It is calculated using the formula KE = 1/2 * mass * velocity^2.
When a ball hits the water, several things happen. Firstly, there is an interaction between the ball and the water molecules. As the ball comes into contact with the water, part of its kinetic energy is transferred to the water molecules. This transfer of energy causes the water molecules to move, creating ripples or waves. Therefore, some of the kinetic energy of the ball is transferred to the water.
Secondly, there is also some energy loss due to other factors such as air resistance, friction, and splashing. These factors contribute to the overall reduction in the kinetic energy of the ball.
As a result, the correct answer is: Some of the energy is transferred to the water. Therefore, overall, kinetic energy is lost when a ball hits the water.
