Stopping Sight Distance given Vehicle Velocity and Reaction Time of Vehicle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sight Stopping Distance = Vehicle Speed*Reaction Time+(Vehicle Speed^2)/(2*[g]*Coefficient of Friction)
SSD = V_speed*t_reaction+(V_speed^2)/(2*[g]*f)
This formula uses 1 Constants, 4 Variables

Constants Used

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

Variables Used

Sight Stopping Distance - (Measured in Meter) - Sight Stopping Distance is the maximum distance a driver can see and stop before colliding with an object or pedestrian on the road ahead.
Vehicle Speed - (Measured in Meter per Second) - Vehicle Speed is the rate at which a vehicle travels and is used to calculate the distance a vehicle can travel before stopping.
Reaction Time - (Measured in Second) - Reaction Time is the time taken by a driver to react to a situation and apply the brakes, affecting the total stopping distance of a vehicle.
Coefficient of Friction - Coefficient of Friction is a dimensionless value that characterizes the frictional force between two surfaces in contact, affecting the sight distance on a road.

STEP 1: Convert Input(s) to Base Unit

Vehicle Speed: 6.88 Meter per Second --> 6.88 Meter per Second No Conversion Required
Reaction Time: 10 Second --> 10 Second No Conversion Required
Coefficient of Friction: 0.8467 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SSD = V_speed*t_reaction+(V_speed^2)/(2*[g]*f) --> 6.88*10+(6.88^2)/(2*[g]*0.8467)

Evaluating ... ...

SSD = 71.6503398554141

STEP 3: Convert Result to Output's Unit

71.6503398554141 Meter --> No Conversion Required

FINAL ANSWER

71.6503398554141 ≈ 71.65034 Meter <-- Sight Stopping Distance
