Answer 1

When apply break the vehicle stops.

Answer 2

First thing is to wear seat belt always. Reason is friction force does not decrease as speed decreases. Thebrakes apply a constant deceleration to the car until the speed is zero. To be accurate, the car does not stop when brakes are applied. The car slows down when brakes are applied, and stops if the brakes are applied long enough to slow it to a stop.
