Breaking Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Breaking Distance = (Speed of Slow moving vehicle^2)/(2*[g]*Design Coefficient of Friction)
BD = (V_b^2)/(2*[g]*f)
This formula uses 1 Constants, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Breaking Distance - (Measured in Meter) - Breaking distance is defined as the distance traveled after applying brake till the vehicle stops.
Speed of Slow moving vehicle - (Measured in Meter per Second) - Speed of Slow moving vehicle is the speed of vehicle which has to be overtaken.
Design Coefficient of Friction - Design Coefficient of Friction is a dimensionless number that is defined as the ratio between friction force and normal force.

STEP 1: Convert Input(s) to Base Unit

Speed of Slow moving vehicle: 11.11 Meter per Second --> 11.11 Meter per Second No Conversion Required
Design Coefficient of Friction: 0.15 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BD = (V_b^2)/(2*[g]*f) --> (11.11^2)/(2*[g]*0.15)

Evaluating ... ...

BD = 41.9552378573043

STEP 3: Convert Result to Output's Unit

41.9552378573043 Meter --> No Conversion Required

FINAL ANSWER

41.9552378573043 ≈ 41.95524 Meter <-- Breaking Distance

LaTeX Go Breaking Distance = Stopping Sight Distance-Lag Distance

Breaking Distance Formula

LaTeX Go

Breaking Distance = (Speed of Slow moving vehicle^2)/(2*[g]*Design Coefficient of Friction)
BD = (V_b^2)/(2*[g]*f)

What is stopping sight distance?

Stopping sight distance (SSD) is the minimum sight distance available on a highway at any spot having sufficient length to enable the driver to stop a vehicle traveling at design speed, safely without collision with any other obstruction.

How to Calculate Breaking Distance?
