Question

An astronaut weights 588 N in Earth surface. How much the astronaut would weight in the surface in the moon in pounds(lbs)?

Answer 1

22.02 lb

Step-by-step explanation:

The weight of astronaut Earth (w) = 588 N

We know that,

`4.45N = 1lb`

Thus,

`588N = (1)/(4.45)* 588lb`

588N = 132.13 lb

Acceleration due to gravity on Earth (g) = 9.8 m/s²

Acceleration due to gravity on Moon = g'

`g'=(g)/(6)`

We know that weight of an object on Earth is,

`w = m* g`

`m = (w)/(g)`

Similarly, weight on Moon will be

`w' = m* g'`

`w' = (w)/(g)*(g)/(6)`

`w' = (132.13)/(6)`

`w' = 22.02`

Thus the astronaut will weigh 22.02 lb on Moon.
