Reaction Time given Stopping Sight Distance and Vehicle Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Constants Used

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

Variables Used

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.
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.
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

Sight Stopping Distance: 61.4 Meter --> 61.4 Meter No Conversion Required
Vehicle Speed: 6.88 Meter per Second --> 6.88 Meter per Second No Conversion Required
Coefficient of Friction: 0.8467 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_reaction = (SSD-(V_speed^2)/(2*[g]*f))/V_speed --> (61.4-(6.88^2)/(2*[g]*0.8467))/6.88

Evaluating ... ...

t_reaction = 8.51012502101539

STEP 3: Convert Result to Output's Unit

8.51012502101539 Second --> No Conversion Required

FINAL ANSWER

8.51012502101539 ≈ 8.510125 Second <-- Reaction Time
