A cat of mass m is sitting at rest on the left sled of two identical sleds, each of mass M, on frictionless ice. It jumps to the right with speed u relative to the ground, turns around on the right sled, and returns to the left sled with horizontal speed u relative to the ground. The final speed of the right sled in terms of m, M and u is:
