Physics Girl also wants to try a fun physics experiment and decides to go bungee jumping. She stands on a bridge that is 100 m above a river and attaches a 30 m long bungee cord to her harness. The bungee cord behaves as an ideal string and has a spring constant of 40 N/m. Assume Physics Girl's mass is 80 kg. How far above the water isPhysics Girl when the cord reaches its maximum elongation?
