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.
