Homework Help: Motion in Space

  1. Nov 19, 2014 #1
    1. The problem statement, all variables and given/known data
    Three uniform spheres are fixed at positions shown in the figure
    If the spheres are in deep outer space and a 0.0150-kg particle is released from rest 300 m from the origin along a line 45∘ below the -x-axis, what will the particle's speed be when it reaches the origin?
    2. Relevant equations

    3. The attempt at a solution
    I calculated the Force on a .015 kg of a particle placed at P
    I also knew the force would be at 45 degrees.
    I don't know how to find the velocity of the particle if it's released 300m from the origin.
