Step-by-step explanation:
The kinetic energy of the marble is converted to elastic potential energy in the rubber ball. When the marble hits the rubber ball, the ball compresses and stores energy in its structure, which is released as it expands back to its original shape. This stored energy is known as elastic potential energy, which is a form of potential energy that depends on the deformation of an object. In this case, the rubber ball deforms when it is hit by the marble, and the deformation results in the storage of energy.
