In this problem we have that if a person weighs 154 pounds, 154 pounds, i'll say lbs, on the earth, what is the person's weight in pounds on the moon? so we have a formula for that.
00:12
We'll say that the weight of someone on the moon is equal to the weight that they have on the earth divided by the acceleration due to gravity on the earth and then multiplied times the acceleration due to gravity of the moon.
00:27
So we have numbers for these, right? we have these established values for the gravity on the earth and the gravity on the moon.
00:34
So we'll say that we can just plug these in.
00:37
We'll say that our weight on the earth is 154.
00:41
We're gonna take that and divide it by the gravity, the acceleration due to gravity on the earth.
00:46
And we know that to be 9 .81, approximately 9 .81 meters per second squared.
00:52
We'll say meters per second squared.
00:54
And then we'll take that and multiply it times the gravity or the acceleration due to gravity that we know to be on the moon.
00:59
And that's 1 .62.
01:01
So 1 point, we'll say 622...
