The acceleration due to gravity on the moon is 1.6 m/s2. What is the gravitational potential energy of a 1200-kg lander resting on top of a 350-m hill?
The formula to calculate gravitational potential energy is P = mgh, where P is the gravitational potential energy, m is the mass, g is the acceleration due to gravity, and h is the height.
Plugging in the given values:
m = 1200 kg
g = 1.6 m/s^2
h = 350 m
P = 1200 kg * 1.6 m/s^2 * 350 m = 672,000 J
Therefore, the gravitational potential energy of the lander is 672,000 J.
