This is an interactive homework problem for introductory physics relating to net displacement of a bobsled completing a double-hill run. It is designed to promote student understanding of how to use the Work-Energy Theorem to solve problems which would be difficult or impossible using the kinematic equations. Given are mass, coefficient of friction, and height of each hill. Students must determine the stopping distance once the bobsled reaches the horizontal plateau. A user-activated "help" sequence is provided to guide students through the problem-solving, from conceptual analysis through quantitative calculation. Immediate feedback is received for both correct and incorrect responses. This item is part of a larger collection of interactive homework problems for introductory physics.
