It's your birthday, and to celebrate you're going to make your first bungee jump. You stand on a bridge 110 m above a raging river and attach a 35-{\rm 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 77 kg. After a long hesitation, you dive off the bridge.
How far are you above the water when the cord reaches its maximum elongation?
