How do you find braking distance when given velocity and reaction distance?
Decrease ..
At 40 mph what is your vehicle and reaction distance?
At 40 mph, a vehicle travels approximately 58 feet per second. The average reaction time for a driver is about 1.5 seconds, which means the reaction distance would be around 87 feet (1.5 seconds x 58 feet/second). Additionally, the stopping distance will vary depending on road conditions and vehicle braking capabilities. Therefore, at 40 mph, the total stopping distance can be around 120-140 feet when factoring in both reaction and braking distances.
Is the stopping distance the same as the following distance?
No, they have different meanings.Following distance is the safe distance to follow behind a moving motor vehicle.Stopping distance is the combination of the drivers reaction time to apply the brakes and the time the vehicle takes to come to a halt.
How long does it take a car traveling 40 mph to come to a complete stop?
For a car with good brakes and a length of 4m, a dry road with a driver with average reaction time it will take approximately 36m/118 feet/nine car lengths for it to stop. This can be divided up into two sections the thinking distance/reaction distance of 12m and a braking distance of 24m. Like the previous answer stated the braking distance can be changed depending on the road surface type and weather conditions or if the car is fitted with an Anti-lock Braking System Thinking distance can be increased by drinking alcohol or taking some types of drugs.
Would the graph of reaction distance versus speed have a positive or a negative slope?
your logic is flawed. please be more specific or present a different relationship in which I can correlate.
