The potential energy of the skater is 2352 J
Explanation:
The gravitational potential energy of a body is the energy possessed by the body due to its position in a gravitational field. Near the Earth's surface, it can be calculated as

where
m is the mass of the body
is the acceleration of gravity near the Earth's surface
h is the height of the body relative to the ground
For the skater in this problem,
m = 60 kg
h = 4 m
Substituting, we find her potential energy:
