Slowing down light to 38 mph
WebbWe can use the kinetic energy idea, and a knowledge of driver reaction times, to write an equation that predicts car stopping distances ("stopping" distance is the sum of reaction and braking distance). Here is the equation's canonical form: Where: = Total stopping distance (reaction + braking), meters. = Vehicle speed, kilometers/hour.
