A rope is tied to a tree limb. It is used by a swimmer
Chapter 6, Problem 6.37(choose chapter or problem)
A rope is tied to a tree limb. It is used by a swimmer who, starting from rest, swings down toward the water below, as in Figure 6.17. Only two forces act on him during his descent, the nonconservative force , which is due to the tension in the rope, and his weight, which is due to the conservative gravitational force. There is no air resistance. His initial height h0 and final height hf are known. Can we use the principle of conservation of mechanical energy to find his speed vf at the point where he lets go of the rope, even though a nonconservative external force is present? (a) Yes. (b) No.
