Assume that friction forces between the cart and the track are negligible, that you are the only passenger in the cart, and that you have a mass of 80 kg. Let the cart have a weight of 4kN. 5. What is name and location of the Roller Coaster that you have chosen to use for your calculations? 6. List the source(s) of information about the Roller Coaster you chose. 7. Calculate the initial Gravitational Potential Energy of the cart and rider before the start of its initial descent. 8. Calculate the Kinetic Energy, the Gravitational Potential Energy and the total Energy of the cart and rider at the bottom of the first loop that it enters. 9. Calculate the Kinetic Energy, the Gravitational Potential Energy and the total Energy of the cart and rider at the top of that first loop.
