Gravitation Problem

  1. Oct 31, 2015 #1
    1. The problem statement, all variables and given/known data
    IF D = 1954 meters and d = -92 meters, to the nearest MN what is the magnitude of the force on the space ship

    2. Relevant equations
    F=(Gmass) / r^2
    F=(G x mass asteroid) / (D/2)^2

    ΣFx= F asteroidright - F asteroidleft = ma

    3. The attempt at a solution
    F asteroid right = F asteroid right = 0N

    However I don't think this right because the ship is moving towards the asteroid on the right

    You are ignoring the fact that the ship is closer to one of the asteroids than to the other? The gravitational force depends only on position and not on velocity.
