1. The problem statement, all variables and given/known data A 70 kg bungee jumper jumps from a bridge. She is tied to a bungee cord whose unstretched length is 13 m , and falls a total of 37 m . Calculate the spring stiffness constant of the bungee cord, assuming Hooke's law applies. 88 N/M Calculate the maximum acceleration she experiences. 2. Relevant equations Spring Force = -k * x F = m * a 3. The attempt at a solution Spring Force = (88 N/M)(24 m) I used 24 m because that was the maximum stretch of the cord. Spring Force = 2,112 N a = F / m a = (2112 N) / (70 kg) a = 88 m/s^2 I added 9.8 m/s^2 because she was in free fall. a = 97.8 m/s^2 Could someone explain why this is incorrect?
