If a car traveling at 50 mph requires 170 ft to stop, find the stopping distance for a car traveling at
v2 = 60
mph.
To find the stopping distance for a car traveling at v2 = 60 mph, you can use the concept of the stopping distance being directly proportional to the square of the velocity.
Let's set up a proportion using the given information:
50 mph is to 170 ft as 60 mph is to x ft.
Mathematically, this can be written as:
50 mph / 170 ft = 60 mph / x ft.
To solve for x, we can cross-multiply:
50 mph * x ft = 60 mph * 170 ft.
Now, we can solve for x:
50x = (60 * 170)
50x = 10200
x = 10200 / 50
x = 204 ft
Therefore, the stopping distance for a car traveling at 60 mph is approximately 204 ft.
To find the stopping distance for a car traveling at 60 mph, you can use the concept of proportional relationships.
We are given that a car traveling at 50 mph requires 170 ft to stop. We can set up a proportional relationship between the speed of the car and the stopping distance.
Mathematically, we have the equation:
50 mph / 170 ft = 60 mph / x ft
To find the value of x, we can cross multiply and solve for x.
Cross multiplying gives us:
50 mph * x ft = 60 mph * 170 ft
Dividing both sides by 50 mph gives:
x ft = (60 mph * 170 ft) / 50 mph
Simplifying gives:
x ft = 204 ft
Therefore, a car traveling at 60 mph would require a stopping distance of 204 ft.
