In the \(xyz\)-coordinate system, a massive particle is initially at rest on a plane whose equation is given below: \[x + 2y + 3z = 0.\] The particle is launched with initial velocity \((v_x,v_y,v_z) = (-3,7,12)\). It travels under the influence of a gravitational acceleration of \((a_x,a_y,a_z) = (0,0,-10)\) until it intersects the plane once more.
When the particle intersects the plane for the second time, how far away is it from the launch point (to 3 decimal places)?
