2352 Joules is the “Gravitational potential energy” that a skater has.
Explanation:
"Gravitational potential energy" of an object is defined as the energy stored in the object which is at a height. Everybody at a height has some energy that is calculated by using the potential energy formula. Mathematically, "Gravitational potential energy" (GPE) is mass (m) times acceleration due to gravity (g) times height (h) of an object. Therefore, GPE = m × g × h.
From the given question,
Mass of the skater is 60 kg
The height at which skater is located is 4 m
“g” is acceleration due to gravity 9.8 [tex]m/s^2[/tex]
Substitute the given values in the GPE = m × g × h
Gravitational potential energy = 60 × 9.8 × 4
Gravitational potential energy = 2352 J .
