Answer:
3080
Explanation:
Potential energy is the energy stored or contained in a body as a result to its relative position to other objects, an example is an object that is placed at a height above the ground thereby experiencing gravitational energy.
Potential energy = mass × gravity × height
Given that: height = 11.08 m, gravity = 9.81 m/s² and mass = mass of boy + mass of ball = 25.1 + 2.94 = 28.34 kg
Potential energy =28.34 × 9.81 × 11.08 = 3080
