The weight of an astronaut plus his space suit on the moon is only 291 n. how much (in n) do they weigh on earth? (the acceleration due to gravity on the moon is 1.67 m/s2.)

Weight on the Moon = 291 N.

W = g · m, where m stays for the mass and on the Moon g = 1.67 m/s²

291 N = 1.67 m/s² · m

m = 291 kg m / s² : 1.67 m/s²

m = 174.25 kg

Weight on Earth = 9.81 m/s² · 174.25 kg = 1,709.4 N

Answer:

The weight of an astronaut on Earth is 1,709.4 N.
