The Gravitational force 2

  1. Oct 5, 2009 #1
    1.Calculate the magnitude of the graviational force exerted on 442kg satellite that is a distance of 1.87 times earth radii from the center of the earth

    For this I used the Newton's law of universal graviation formula: F=(g*m1*m2)/r^2
    ((6.67*10^-11)(442)(5.98*10^24))/(Radius of the earth(6.38*10^3) * 1.87=11930.6)^2

    a.) What is the magnitude of the gravitational force exerted on the earth by the satellite?
    I would think it's the same answer as number 1.

    b.) Determine the magnitude of the satellite's acceleration

    c.)What is the magnitude of the earth's acceleration
    a=2.0712 *10^-17

    but it's wrong what am I doing wrong?
    Thank you~!

    What are the units in that value?
