You step into the role of a forensic crash investigator. A calm weekday morning is interrupted when a car leaves the road and slams into a tree. The driver insists he braked as soon as the danger appeared. His wife claims he was travelling far faster than he admits. Investigators arrive to find a short but clear set of skid marks, a damaged front end, and two conflicting stories.
Using braking-distance equations, reaction-time analysis, and standard stopping-distance models, you’ll reconstruct the final seconds before impact. Was this an unavoidable accident… or does the maths tell a different story?
