The correct answer is d) Both objects have the same amount of kinetic energy.
The kinetic energy of an object depends on its mass and velocity. From the diagram, we can see that both objects are at the same height, which means they have the same potential energy. When the objects are released, they will both fall downwards and accelerate due to gravity. As they fall, their potential energy will be converted into kinetic energy. Since both objects are identical, they will have the same mass and fall with the same acceleration. Therefore, they will have the same velocity and the same amount of kinetic energy.
In the diagram below, two identical objects are released from rest at the starting position. Object 1 was released first and sometime later Object 2 was released. The diagram below shows the positions of Objects 1 and 2 a short time after both were released.
Which object in the figure has the most kinetic energy?
a
Object 2
b
Object 1
c
Neither object has any kinetic energy.
d
Both objects have the same amount of kinetic energy.
