Solution: Ginger (mass 60 kg) uses a 3.5-m-long rope to pull Sandra (mass 70 kg) across the floor at a constant speed of 1.3 m/s. The rope has a mass of 120 g. Sandra signals to Ginger by plucking the rope, sending a wave pulse. The pulse reaches Ginger 200 ms later. What is the tension in the rope?
