If the speed of a car is increased by 35%, by what factor will its minimum braking distance be increased, assuming all else is the same? Ignore the driver's reaction time.

Answer 1

Braking distance increases with the square of the initial velocity, because it depends upon the car's initial klietic energy.

What is the square of 1.35?

Answer 2

oh right!! i forgot about square rooting 1.35.
thank you!
