In bungee jumping, a bungee jump is the amount the cord will stretch at the bottom of the fall. The stiffness of the cord is rel
ated to the amount of stretch by the equation given below. K = [(2W(S+L)]/(S^2) W= weight K = cord stiffness (pounds per foot) L = free length of cord (feet) S = stretch (feet) (a) A 190-pound person plans to jump off a ledge attached to a cord of length 52 feet. If the stiffness of the cord is no less than 28 pounds per foot, how much will the cord stretch?
