This item is a 2-day experiential learning activity for introductory physics relating to circular motion and friction. In this scenario, students design a flat circular highway exit and determine, within a set of given constraints, what the exit speed limit should be. True to the PBL method, students will sift through information to separate useful from irrelevant data, locate missing information on their own, and then apply physics in finding solutions. This resource includes a printable student manual and a password-protected teacher's guide with solutions and tips for instructors. SEE RELATED ITEMS for a link to the full collection of PBL exercises by the same authors.
