Conservation of energy - pendulum

  • #1
If I have a person swinging on a rope (like a pendulum) and I know the height above the reference level that the person starts swining from, as well as the length of the rope and the person's mass and weight... how can I find tension in the rope? Is tension constant throughout the entire swing? My first thought was that the tension is not constant, and is at a maximum when the rope is hanging straight down, but how do I know if this is true?


Thanks

Try looking at the forces at some angle displaced from its rest position.
