If the braking distance of a medium sized car that is going at 50 miles per hour, it's braking disatnce is about 200 feet.
Does it take twice as far to stop a car that is going twice as fast? Explain. Thanks. Please help.
Energy is half the mass times the square of the velocity.
$$2^2=4$$ (This 2 represents the (doubling) increase in velocity)
Disregarding other considerations, it will take 4 times the distance.
Thanks, 7UP. So, it is 4 times the distance for the car to come into a complete stop?
