Physics 20-1 Dynamics

  1. Nov 23, 2014 #1
    1. The problem statement, all variables and given/known data
    A 4.7x10^3 kg asteroid is acted on by a gravitational force of 2.0x10^2 N from another asteroid that is 3.0x10^2 km (3.0x10^5 m) away. What is the mass of the second asteroid?

    2. Relevant equations
    The equations we have been working with are
    356ed489deee0677da9532e2b8acd432.gif in which G is 6.67*10-11Nm^2/Kg^2
    and
    137cc55ed7f4746b8a247ad69d64a9a5.gif
    But we don't have the information to use the second one

    3. The attempt at a solution
    356ed489deee0677da9532e2b8acd432.gif in which I solved for m2
    b8742161d05cb531c479ec95e1cdcf94.gif
    = 581ea9c349629a8e470f173dff0d6fef.gif
    =5.74*1019 kg

    The number is huge though which makes me think that I did something incorrect or used the wrong formula
