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).
Explanation
Resonance:
1. The amplitude of vibration is very large.
2. The vibrations of the body are in phase with the external periodic force.
Forced Vibrations:
1. The amplitude of vibration is usually small.
2. The vibrations of the body are not in phase with the external periodic force.
