Question: A stone is dropped at t = 0. A second stone, with twice the mass of the first, is dropped from the same point at t = 115 ms.

Part A: How far below the release point is the center of mass of the two stones at t = 392 ms?

I need help to find how far below the release point is the center of mass of the two stones.
