2 A bungee jump is set up on a bridge 40 m above the water. The spring constant of the bungee cord is 725. The formula to show the relationship between the mass of the bungee jumper and the extended length of the bungee cord beyond it's original unstretched length is : Ist semester (2 . m . 9.8 . 40) Performance Naiya Miller 1 : 725 Final Exam * complete 2 out of 3 m is the mass of the jumper and I is the extended length of the bungee cord. The graph showing the length of a bungee cord extension in relation to the mass of the bungee jumper is shown below. 20 15 10 - Max Bungee Cord Length Beyond Unstretched (m) 40 60 80 100 120 20 140 160 0 Mass (kg)part A: The bungee cord should be stretched 12 m or less beyond it's original length or it will break. What is the highest mass of bungee jumper that should be allowed to jump? a kg Part B: The bungee cord should stretch 8 m or more beyond it's original length.
