Question

In a closed system, there is 500 J of potential energy and 800 J of kinetic energy and no other forms of energy are present in this
system. Ten years later, the kinetic energy is measured at 300 J. After 10 years, the amount of potential energy is:
O 300 J.
O 800J.
O 500 J.
O 1000 J

Answer 1

Answer:

I think the answer is 800J

Explanation:

As the kinetic energy goes down, the potential energy goes up
