Step-by-step solution
What Is Braking Distance?
Braking distance is the distance a vehicle travels after the brakes are applied until it stops. It depends on speed, road conditions and friction.
How is it calculated?
How Is It Calculated?
Braking distance = v² ÷ (2 × μ × g)
v: speed (m/s), μ: coefficient of friction, g: 9,81 m/s².
- Enter the speed and the road friction coefficient.
Frequently Asked Questions
What happens to braking distance when speed doubles?
Since it is proportional to the square of the speed, the braking distance becomes four times as long.
