Question

An astronaut has a mass of 125 kilograms on Earth. He then travels to Neptune. On Earth g = 9.8 m/s^2; on Neptune g = 1.1 m/s^2

Answer 1

Answer:

See below

Explanation:

I'm assuming the question is asking how much the astronaut weights on Earth and Neptune.

The astronaut's Mass would be exactly the same on Earch as it is on Neptune since mass does not change based on gravity.

Weight = Mass x Gravity

Weight on Earth = Mass x Gravity on Earth

W = 125kg x 9.8 m/s²  = 1225 kg m / 2²  which is 1225 N (Newtons)

Weight on Neptune = Mass x Gravity on Neptune

W = 125kg x 1.1 m/s²  = 137.5 kg m / s²   or 137.5 N
