Calculates the Minimum Speed/Velocity of a vehicle that is skidding/decelerating based on its skid distance, braking efficiency, roadway grade and the vehicle’s final/impact velocity.

Calculations are completed in fps and mph when using the Imperial System and m/s and km/h in the Metric System.
In addition to the speed calculations, the time elapsed in the skid is determined as well as the adjusted drag factor.

The coefficient of friction, vehicle braking efficiency and roadway grade, are all entered via sliders or text fields. When the slider for any of the related values is moved, both the value of the related item and all of the related calculations are instantly changed. This allows the investigator to instantly determine how sensitive the values are to the speed calculations.
