Explanation:
Potential energy = Mass x Acceleration due to gravity x Height
Mass = 114 kg
Height = 4 m
Acceleration due to gravity = 9.81 m/s²
Substituting
Potential energy = Mass x Acceleration due to gravity x Height
Potential energy = 114 x 9.81 x 4
Potential energy = 4473.36 J
The increase in the gravitational potential energy of the man-earth system is 4473.36 J
