Answer: The weight of the astronaut on earth is greater than his weight on the moon.
Explanation:
The reason I got this answer is because the astronaut will have the same mass on the moon as he does on earth. Also the weight of a person or object is determined by gravity. So since the moons gravity isn’t as strong as earths gravity the astronauts are lighter in terms of weight, and this is how they slightly float.
Position <em>' C '</em> is the middle of the swing. That's where the weight is the lowest.
It's also the place where the weight is moving the fastest, so that means it's the place where the kinetic energy is greatest.
