The correct answer is: She is correct because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground.
To determine whether she is correct or incorrect about the relationship between the height a ball is dropped from and its kinetic energy when it hits the ground, we need to understand the concept of kinetic energy.
Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass and velocity of the object. The formula for calculating kinetic energy is KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is its velocity.
Now, think about what happens when a ball is dropped from different heights. When the ball is dropped from a higher height, it has more potential energy (energy stored due to its position) because it is higher above the ground. As it falls, this potential energy is converted into kinetic energy. The ball gains speed (velocity) and its mass remains constant.
According to the formula for kinetic energy, the velocity of the ball is squared. This means that the increase in kinetic energy is proportional to the square of the ball's velocity. So, when the ball is dropped from a higher height, it gains more speed and therefore has a greater velocity when it hits the ground. This increase in velocity results in a larger amount of kinetic energy.
Based on these explanations, we can conclude that she is correct because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground. Therefore, the correct statement is: "She is correct because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground."
