This item is a PBL (Problem-Based Learning) activity for introductory physics relating to conservation of momentum, frictional force, and kinetic energy. This scenario involves a crash in which a small car is struck broadside by a vehicle of more than double its mass. Students must determine whether either driver engaged in reckless driving. To solve the problem, students work cooperatively to calculate the coefficient of friction on the roadway, velocity of each vehicle at the time of the crash, and velocity of the vehicles prior to braking. They will use a combination of strategies: Work-Energy Theorem and kinematic equations.
In keeping with 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 to real-life problems.
This resource includes a printable student manual and a password-protected teacher's guide with solutions and tips for instructors. (Accessing the teacher's guide requires registration with the authors.) SEE RELATED ITEMS ON THIS PAGE for a link to the full collection of PBL exercises by the same authors.

6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.
6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
9-12: 4F/H7. In most familiar situations, frictional forces complicate the description of motion, although the basic principles still apply.
9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.
12. Habits of Mind
12B. Computation and Estimation
9-12: 12B/H2. Find answers to real-world problems by substituting numerical values in simple algebraic formulas and check the answer by reviewing the steps of the calculation and by judging whether the answer is reasonable.
9-12: 12B/H3. Make up and write out simple algorithms for solving real-world problems that take several steps.
12D. Communication Skills
9-12: 12D/H1. Make and interpret scale drawings.
9-12: 12D/H7. Use tables, charts, and graphs in making arguments and claims in oral, written, and visual presentations.
9-12: 12D/H8. Use symbolic equations to represent relationships between objects and events.
