Answer: The potential energy in the system is greatest at X
Explanation: Potential energy is how much energy an object can have. Gravity has an effect on potential energy, the higher something is, the more potential energy it has. For example, if you hold a book above your head, that book has potential energy. When you drop the book, it has kinetic energy. Therefore, since point X is the highest point, the ball has the greatest potential energy there.
