Answer 1

It’s OJ because mechanical energy can give off the same

Answer 2

The kinetic energy is 0J

Explanation: Mechanical energy is as much of potential and kinetic energy. Mechanical energy is never lost but only transformed from one form to another. As long as all the mechanical energy is as much as the potential energy then the kinetic energy is 0J. The mechanical energy of an object is found by summing its potential energy and kinetic energy.
