Question

Select the correct answers.
Which statements about braking a car are true?
The greater the kinetic energy of a car, the longer it takes for the car to stop.
The lower the kinetic energy of a car, the longer it takes for the car to stop.
If the speed of a car doubles, the car’s kinetic energy and braking distance quadruple.
If the speed of a car doubles, the car’s kinetic energy and braking distance remain the same.

Answer 1

please help

Answer 2

So we can eliminate the first two because it has nothing to do with the kinetic energy of a car, So, we are left with options 3,4

3.)If the speed of a car doubles, the car’s kinetic energy and braking distance quadruple.
(The only one that makes sense.)

X.)If the speed of a car doubles, the car’s kinetic energy and braking distance remain the same.
(If it doubles, then the distance has to be longer)
