Because the act of braking is an example of negative acceleration.
Example: if the rate of braking was say 2 meters per second^2, and the starting velocity was 10 m/s, it would take 5 seconds to come to a stop(during those 5 seconds you would still be moving).

Answer:
electromotive force
Explanation:
This force is called electromotive force, or EMF. Sometimes it is convenient to think of EMF as electrical pressure. In other words, it is the force that makes electrons move in a certain direction within a conductor
(a) The car is undergoing an acceleration of
so that in 9.02 s, it will have covered a distance of
The car has tires with diameter <em>d</em> = 58.5 cm = 0.585 m, and hence circumference <em>π d</em> ≈ 1.84 m. Divide the distance traveled by the tire circumference to determine how many revolutions it makes:
(b) The wheels have average angular velocity
where is the average angular velocity, and are the initial and final angular velocities (rev/s), and are the initial and final angular displacements (rev), respectively, and is the duration of the time between initial and final measurements. The second equality holds because acceleration is constant.
The wheels start at rest, so
