If an astronaut has a weight of 450 n on the earth, what would be her weight on the moon? a. 101 ib в. 46 n c. 77 n d. 7.8 n

Explanation:

Given that,

Weight of the astronaut on the surface of Earth, W = 450 N

We know that the acceleration due to gravity on the earth is,

Weight of an object is given by, W = mg

m = 45.91 kg

Also, the acceleration due to gravity on the surface of moon is one -sixth of the acceleration due to gravity on the surface of Earth,

As mass remains constant. So, the weight on the moon is :

W' = mg'

W' = 74.37 N

Hence, this is the required solution.
