An 114 kg man climbs up a 4 m high fight of stairs. the acceleration of gravity is 9: 81 m/s2. what is the increase in the gravitational potential energy of the man-earth syste

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
