It may be useful now to do a little bit of research on the physics of rollercoasters. You will not need to do any physicsstyle calculations in this assignment, but you will be expected to abide by the common rules. For example, a rollercoaster cannot be expected to defy gravity after the initial drop; it must be given momentum at the beginning of the track, and cannot reach as high a height at the end of its track as it can at the beginning. Also, it must run on a smoothly curving, connected track. a short paragraph describing What you found and cite your sources (\"l2 sources)
