Two space walkers, one with a mass of 77 kg and the other with a mass of 78 kg, hold on to the ends of a lightweight cable 14.5 m long. The astronauts are originally at rest in deep space. If the astronauts then start pulling themselves toward each other hand-over-hand along the cable until they meet, how far will the less massive astronaut move?
