Question
Iesha drops a ball from three different heights, as shown.
For each drop, she calculates what the kinetic energy of the ball would be when it hits the ground. The table shows her data.
Height of Drop (meters) Kinetic Energy (joules)
1.0 48
1.5 72
2.0 96
Iesha says that a ball dropped from a height of 3.0 meters would have less than 96 joules of kinetic energy when it hits the ground. Is she correct and why?
A.
She is correct because the higher the ball is dropped from, the less kinetic energy it will have when it hits the ground.
B.
She is correct because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground.
C.
She is incorrect because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground.
D.
She is incorrect because the higher the ball is dropped from, the less kinetic energy it will have when it hits the ground.

The correct answer is:
C. She is incorrect because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground.
The data shows that as the height from which the ball is dropped increases, the kinetic energy when it hits the ground also increases. Therefore, a ball dropped from a height of 3.0 meters would have more than 96 joules of kinetic energy, not less.
