Answer:
The GPE, stored is 640 Joules
Explanation:
The given parameters are;
The given mass of the astronaut, m = 80 kg
The height of the top of the lunar lander to which the astronaut climbs, h = 5 m
The gravity strength on the moon, g = 1.6 N/kg
The Gravitational Potential Energy, GPE, stored is given according to the following equation;
GPE stored = m·g·h
Therefore, by substituting the known values, we have;
GPE Stored = 80 kg × 1.6 N/kg × 5 m = 640 Joules
The GPE, stored = 640 Joules.
