Weight of an astronaut and his space suit on Earth is 60 kgf and 30 kgf respectively. Their combined weight on Moon will be
Combined weight of astronaut and his space suit on Earth = 60 kgf + 30 kgf = 90 kgf
Since weight of an object on Moon is one-sixth of that on the Earth, the combined weight of the astronaut and his space suit on Moon is 906 kgf = 15 kgf
