A student drops a ball three different times.
The table shows the ball’s kinetic energy upon hitting the ground from different heights.
Height of Drop (Meters) Kinetic Energy (Joules)
1.0 48
1.5 72
2.0 96
The student claims that a ball dropped 3.0 meters would have fewer than 96 joules of kinetic energy upon hitting the ground. Is she correct? Why?
She is wrong. The higher the drop, the less kinetic the ball will have upon hitting the ground.
She is right! The higher the drop, the greater kinetic the ball will have upon hitting the ground.
She is right! The higher the drop, the less kinetic energy the ball will have upon hitting the ground.
She is wrong. The higher the drop, the more kinetic energy the ball will have upon hitting the ground.
Anyone can Help me?
The correct answer is: She is right! The higher the drop, the greater kinetic energy the ball will have upon hitting the ground.
This is because kinetic energy depends on both the mass of the object and its velocity. When an object is dropped from a higher height, it gains more potential energy, which is then converted into kinetic energy as it falls. As the ball falls, its velocity increases, which increases its kinetic energy. So, the ball dropped from 3.0 meters would have more than 96 joules of kinetic energy upon hitting the ground.
Yes, I can help you. The correct statement is: "She is wrong. The higher the drop, the more kinetic energy the ball will have upon hitting the ground."
This can be observed from the given table. As the height of the drop increases, the kinetic energy of the ball also increases. More specifically, the kinetic energy is directly proportional to the height of the drop. Therefore, if the student claims that a ball dropped from 3.0 meters would have fewer than 96 joules of kinetic energy, she is incorrect.
