A car traveling at 30 mph can stop in about 100 ft. How far does it take for the same car to stop if it is traveling at 60 mph?
d = (60/30)^2 * 100 Ft = 400 Ft.
how far will a car moving at 20 m/s travel in one minute?
how far will a car moving at 20 m/s travel in one minute?
To find out how far a car traveling at 60 mph takes to stop, we can use the concept of braking distance. Braking distance is the distance a car travels from the moment the brakes are applied until it comes to a complete stop.
In this case, we are given the braking distance for the same car traveling at 30 mph, which is 100 ft. We can use this information to determine the braking distance at 60 mph.
The braking distance of a car is directly proportional to the square of its speed. This means that if the speed doubles, the braking distance will be four times longer.
To find the new braking distance, we can use the following formula:
Braking distance2 = (Speed2 / Speed1^2) * Braking distance1
Where:
- Speed1 is the initial speed (30 mph)
- Speed2 is the new speed (60 mph)
- Braking distance1 is the initial braking distance (100 ft)
Plugging in the values, we have:
Braking distance2 = (60^2 / 30^2) * 100
Simplifying the equation gives us:
Braking distance2 = (3600 / 900) * 100
Braking distance2 = 4 * 100
Braking distance2 = 400 ft
Therefore, a car traveling at 60 mph would take approximately 400 ft to come to a complete stop.
