You have just started a bungy Jump business called Go Jump. A jump platform has been built that is 50 m above a river bend where the depth of the river is 4 m. The grand opening will be in two weeks’ time. As part of the grand opening, you are also demonstrating, for the first time, a new type of bungy cord made from an innovative ultra light material. The grand opening will be attended by the Victorian Minister for Tourism and Major Events to promote exciting tourism businesses and innovations in technology. The media will be a plenty.
As a precaution, you have decided that you will be first jumper to test the platform. You want to ensure that maximum wow factor is achieved by setting the jump such that you touch the water. Unfortunately, the new cord has not yet been tested and has no specs. How should you set up your jump to ensure that everything goes smoothly with no accidents or incidents with the first jump during the grand opening?
Learning Objectives:

Students must work in teams of 2 – 4 students
(This is to reinforce collaborative and peer learning, individual submissions will not be accepted)
Solutions Submission
Your submission needs to:
- reference the source of any information that you use in your solution.
- justify solutions with appropriate comments.
- describe the physics involved to demonstrate that you understood the physics and achieved the learning objectives. No evidence of understanding of physics will not receive any marks.
- Be typed or written in clearly and neatly.
On your submission,
- clearly state the full names and IDs of the team members.
- Indicate which tutorial group you belong to.
- include the Problem Identification worksheet.
This problem is worth 2 marks.
Additional spplementary information about this problem is required to solve this problem. This supplementary information will be only be released to groups who have completed the first 2 steps in the Defining Learning Issues worksheet. If you did not receive the supplementary materials in the first class, email your team’s Defining Learning Issues worksheet with steps 1 and 2 completed to the lecturer to receive the supplementary material.
