Title: A Bad Day for Sandy Dayton

For a group question on the exam, I wrote a short problemwith some common elements of Sandy Dayton (a car is parked on the side of the street, and a truck hits it. Students were required to find the speed of the truck prior to hitting the brakes based on evidence found at the scene of the accident, including skid marks.

Shorter homework problems can include having students sketch graphs of the motion of an object at constant speed, slowing down speeding up, etc. Also ask questions about motion resulting from balanced and unbalanced forces.
