WebThe mathematical law which relates skid distance to speed is stated thus: The skid distance is proportional to the square of the speed. This means that, like the energy of a moving vehicle, the skid distance is quadrupled when the speed is doubled. Thus, if a car skids 30 feet at 30 miles per hour, it will skid 120 feet at 60 http://www.anycalculator.com/skidspeed.htm

WebThe over-used SKID TO STOP formula is only appropriate when called upon to calculate the initial (i.e., beginning) speed of a vehicle found to have skidded to a stop. In its most basic form, this equation ( Eq. 1 ) takes the form: S = {30Df} 1/2 (Eq. 1) where, S = speed in miles per hour (MPH), D = skid distance, in feet, and f = drag factor. WebOct 20, 2024 · Simply put, the speed of the vehicle is equal to 15.9 times the square root of the skid distance multiplied by the coefficient of friction for the road surface.
