Solution: Its your birthday, and to celebrate you're going to make your first bungee jump. You stand on a bridge 120 m above a raging river and attach a 33-m-long bungee cord to your harness. A bungee cord, for practical purposes, is just a long spring, and this cord has a spring constant of 43 N/m . Assume that your mass is 76 kg . After a long hesitation, you dive off the bridge. How far are you above the water when the cord reaches its maximum elongation?
