Astone is dropped at t = 0. a second stone, with 5 times the mass of the first, is dropped from the same point at t = 180 ms. (a) how far below the release point is the center of mass of the two stones at t = 420 ms? (neither stone has yet reached the ground.) (b) how fast is the center of mass of the two-stone system moving at that time?
