Question

What is the weight of a 90 kg astronaut on the moon? (gravityON 1200kgon the moon is 1.62 m/s/s)

Answer 1

The weight of astronaut on the moon is,

`W=mg`

Plug in the known values,

`\begin{gathered} W=(90kg)(1.62m/s^2)(\frac{1\text{ N}}{1kgm/s^2}) \\ =145.8\text{ N} \end{gathered}`

Thus, the weight of astronaut on moon is 145.8 N.
