Take D = 50.0 m, F = 110 N, L = 40.0 m, and = 50.0. Therefore, there is no need to solve for the speed of the rollercoaster at Point C. You can set up the Conservation of Energy equation between Point A and Point D. However, it is perfectly fine to solve the intermediate step of finding the velocity at Point C if you like. The chain return is now usually located inside the spine of the track rather than a separate component. This makes physical sensestopping force takes energy out of the system and so MathJax reference.
