So in this question, we're told a woman has a mass of 55 kilograms.
00:06
We're asked to calculate her weight on earth, and we're asked to calculate her mass and her weight on the moon, where we have a different acceleration due to gravity of 1 .62 meters per second squared.
00:21
So in the first part of this question, part a, we need to calculate the weights of the person standing on.
00:32
On earth.
00:33
So typically we would use a w for that or sometimes we just write that as the force due to gravity.
00:39
And so this is pretty easily calculated just as m times g.
00:43
So her weights on earth is 55 kilograms times the acceleration due to gravity on earth, which is 9 .81 meters per second squared.
00:54
So the weight of this woman on earth, if you plug that into your calculator, you a value of about 540 newtons.
01:06
So i'll just label this as earth.
01:10
And this is her weight here.
01:12
This is the final answer...
