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 represents the distance a vehicle will travel while the driver is reacting to something they see ahead.
Vehicle Speed - (Measured in Meter per Second) - Vehicle Speed refers to the rate at which a vehicle is traveling.
Reaction Time - (Measured in Second) - Reaction Time is the time taken to complete a reaction to a certain extent.
Coefficient of Friction - 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

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: 0.2 --> 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]*0.2)

Evaluating ... ...

SSD = 80.8669137778956

STEP 3: Convert Result to Output's Unit

80.8669137778956 Meter --> No Conversion Required

FINAL ANSWER

80.8669137778956 ≈ 80.86691 Meter <-- Sight Stopping Distance
