  1. Dec 10, 2007 #1
    I'm trying to help a friend out, would anyone be willing to be an extraordinary help and simply plug in the numbers for this formula and let me know the answer? It would be greatly appreciated.

    2. Relevant equations

    m = 7.35 x 10^22kg
    r = 3.84 x 10^8

    Thank you!

    2.0027443773 x 10^20 (kg*m/s/s)

    Might be a little off, I haven't calculated such big numbers in my head in a long time.
    Hope that helps!

    How did you know it was meters???? Amazing. It's the force exerted by the earth on the moon, isn't it?

    Haha, yeah you're right. I was hoping the 11 or so significant digits would be the funny part but the joke ended up being on me. And yeah, that's the distance to the moon from the earth.

    Not at all, you were pretty funny as well. Goosey23, you just wanted a confirmation, right? You do know how to calculate that?
