If a rope of mass 10 kg is connected to a hook on the top and is supporting a mass of 15 kg at the bottom, what is the rope's tension?
What is the tension and density of a rope supporting a mass of 15 kg?

SUMMARY
The tension in a rope supporting a mass of 15 kg, with the rope itself weighing 10 kg, varies along its length. The tension at any point in the rope is determined by the weight of the rope below that point plus the weight of the 15 kg mass, equating to 147 N (15 kg * 9.81 m/s²). To calculate the density of the rope, the total mass of the rope (10 kg) must be divided by its length, which is not specified in the discussion but is essential for determining density in kg/m.
