A stone is dropped at t = 0. A second stone, with 5 times the mass of the first, is dropped from the same point at t = 74 ms. (a) How far below the release point is the center of mass of the two stones at t = 270 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?
