Two particles are traveling through space. At time t, the first particle is at the point (3t, -5 + 2t, 5 + 3t) and the second particle is at (-1 - t, 3 - 2t, 15 - 2t). Describe the two paths in words. Then determine if the two particles collide, cross, or neither cross nor collide to fill in the following: If they collide or their paths cross, indicate where (if neither is true, enter none): collision or crossing occurs at (x, y, 2).
