Introduction

Can a roller coaster by built to exceed all known records without sacrificing the safety of its riders?

Your mission is to design a rollercoaster that will exceed all current records for height, slope, and speed. Your design must include calculations to verify that your design meets all requirements. In trials of a model of your design, a marble placed at the start of the rollercoaster must successfully navigate the entire rollercoaster with out stopping and/or receiving outside power other than the initial push. A final presentation will be made to the presidents of both companies involved.  The winning design will be greatly rewarded for all of there hard work.
