WebAs with all other calculators, please do not use it in any legal proceedings. Example 1: Calculate the distance necessary to stop a car moving at 90 km/h on a horizontal wet asphalt concrete (coefficient of friction μ = 0.4) if the driver perception time is 0.5 s and reaction time is 0.7 s. Example 2: Calculate the initial speed of the car ...

WebReaction time. One reason for this increased risk is reaction time—the time it takes between a person perceiving a danger and reacting to it. Consider this example. Two cars of equal weight and braking ability are travelling along the same road. Car 1, travelling at 65 km/h, is overtaking Car 2, which is travelling at 60 km/h. WebWe know that displacement is the same thing as average velocity times change in time (displacement=Vavg*(t1-t2)). Right now we have something in terms of time, distance, and average velocity but not in terms of initial velocity and acceleration. We know that average velocity is the same thing as initial velocity (vi) plus final velocity (vf ...
