The weight of an astronaut plus their space suit on the Moon is only 250 N.

(a) How much does the suited astronaut weigh on Earth?
(b) What is the mass on the Moon? On Earth?

A. (a) 1,625 N, (b) 25.5 kg on the Moon, 165 kg on Earth
B. (a) 1,625 N, (b) 25.5 kg on the Moon, 250 kg on Earth
C. (a) 2,500 N, (b) 40.0 kg on the Moon, 250 kg on Earth
D. (a) 2,500 N, (b) 40.0 kg on the Moon, 165 kg on Earth

Answer :

Final answer:

The suited astronaut weighs 1,625 N on Earth and has a mass of 25.5 kg both on the Moon and on Earth.

Explanation:

(a) How much does the suited astronaut weigh on Earth?

To find the weight of the suited astronaut on Earth, we can multiply the weight on the Moon (250 N) by the acceleration due to gravity on the Moon (1/6 times the acceleration due to gravity on Earth). Therefore, the suited astronaut weighs 1,625 N on Earth.

(b) What is the mass on the Moon? On Earth?

Mass does not change with location, so the mass of the astronaut remains the same on the Moon and on Earth. Therefore, the mass is 25.5 kg both on the Moon and on Earth.
