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

Solution :

weight of Astronaut on Earth :

• $mass \times acceleration \: \: due \: \: to \: \: earth$

• $125 \times 9.8$

• $1225 \: \: \: newtons$

weight of Astronaut on Neptune :

• $mass \times accelertion \: \: due \: \: to \: \: neptune$

• $125 \times 1.1$

• $137.5 \: \: newtons$
