Question

Can anyone figure out what I'm doing wrong??

Answer 1

there, my ages are all good, it's the freaking masses for some planets that dont match up

Answer 2

You're probably using different conversions than he does...

Answer 3

I guess.. I'll just email him and ask what's going on.

Answer 4

It's just saturn, uranus and neptune are way off

Answer 5

I still never understood why you used the G values for the planets when the assignment gives you the correct conversions..

Answer 6

wait what do u mean?

Answer 7

ohh I think im startin to see it..

Answer 8

The original assignment said something like: mars has a gravity 63% of earths or something like that.

Answer 9

that means that your weight on mars will be 63% your weight on earth.

Answer 10

no need to go into the whole mass/g/etc.

Answer 11

LOL I didn't even notice.. let me check..

Answer 12

It actually doesn't..

Answer 13

I thought they gave you a table.

Answer 14

Where's the assignment?

Answer 15

yea they did

Answer 16

Hold up ill repost it

Answer 17

here

Answer 18

But there's another thing, like all those websites that calculate it for you are getting exactly professor's answer, so are they off by rounding too?

Answer 19

So yeah, they give the % conversions because the person they give as an example weighs 100 lbs and then they say he weighs 38lbs on Mercury. Therefore mercury is 38% earths gravity.

Answer 20

so I suspect if you used those % conversions you'd get the same numbers.

Answer 21

Most likely you're being too exact ;p

Answer 22

I like being exact haha.. so instead of doing
Weight on Mercury = mass on earth * g of mercury
I just do:
weight on mercury = mass on earth * 0.38

Answer 23

Right.
