Hello, here we have to solve the following problem.
00:03
On the earth the astronaut weighs 241 pounds and we have to determine weight on the moon.
00:15
Weight on the moon equals to mass of the astronaut times g on the moon, which is weight of the earth, weight in the earth divided by g on the earth times g on the moon.
00:28
That is 241 over 6 pounds.
00:32
Now let's calculate it.
00:37
That's 40 .2 pounds.
00:40
All right, now in question b we have to determine and actually in question a we have to convert it to newtons.
00:53
Let's do this.
00:54
So 241 pounds is equivalent to 109 kilograms.
01:02
So it means that weight on the moon is 109 kilogram times 9 .8 meters per square second divided by 6.
01:17
That's 178 newtons.
01:19
All right, now in question b we have to find weight on the mars...
