Explanation:

Energy is commonly defined as the ability to do work. Mechanical energy is a type of energy possessed by an object when I motion (moving) or in a position (resting).

Mechanical energy has two types viz: kinetic energy and potential energy. Kinetic energy is the energy possessed by a moving object while potential energy is that possessed at a fixed position.

Therefore, in this question, all the examples portrays a moving or stationary object, which makes all an example of mechanical energy. Bouncing ball (moving), water in a reservoir (stationary), book on a table (stationary), person running (moving) etc.
