First Law of Thermodynamics:
1. Stone Mountain near Atlanta, GA has a sky ride which a gondola is suspended from a cable that takes people to the top of Stone Mountain as well as back down. [MO4, MO5, MO6]
2. Using the First Law of Thermodynamics, what would be the most efficient way to design this ride?
3. Discuss if this might be used to generate rather than use electrical energy. If so, what would be required? If not, why not?
