What is the skid to stop formula?

The skid to stop formula is used to calculate the stopping distance of a vehicle that is skidding to a stop. It is given by the equation ( d = \frac{v^2}{2 \mu g} ), where ( d ) is the stopping distance, ( v ) is the initial velocity, ( \mu ) is the coefficient of friction between the tires and the road, and ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 )). This formula assumes that the vehicle is skidding and does not account for any braking forces applied.
