Determine the specifications (unstretched length and spring constant) for the elastic cord to be used at a bungee-jumping facility. Participants are to jump from a platform 150 ft above the ground. When they rebound, they must avoid an obstacle that extends 15 ft below the point at which they jumped. In determining the specifications for the cord, establish reasonable safety limits for the minimum distances by which participants must avoid the ground and obstacle. Account for the fact that participants will have different weights and heights. If necessary, specify a maximum allowable weight for participants. Write a brief report presenting your analyses and making a design recommendation for the specification of the cord.
