The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that the cords are 10 m long when relaxed and that the jumper starts at the anchor. Also, the cords stretch an additional length 24 m for a jumper whose mass is 82 kg, the heaviest person allowed to use the bungee jump (heavier people will hit the ground). At the instant where the tension in the cord is greatest (at what stage of the motion does this happen?), what is the jumpers speed? Throughout this problem, use g = 9 . 8 m / s 2 ....
