## Detail Page

This interactive homework problem asks the student to determine the time needed to stop a car given the initial velocity and stopping distance. A sequence of questions designed to encourage critical thinking and conceptual analysis is included. It is part of a larger collection of interactive problems developed by the Illinois Physics Education Research Group.
Editor's Note: Relating the graph to the motion can be tricky in cases where an object slows down at a constant acceleration. This interactive problem provides wonderfully clear drawings to help students recognize how constant negative acceleration appears graphically. It also gives a little nudge to help kids do the math as efficiently as possible, without spoon feeding.
