Final answer:
The factors that influence how long it takes a vehicle to stop are velocity, driver reaction time, and road conditions.
Step-by-step explanation:
The factors that influence how long it takes a vehicle to stop are:
- Velocity: A car's initial velocity affects the stopping distance. For a given acceleration, a car that is going twice as fast does not stop in twice the distance.
- Driver Reaction Time: The time it takes for a driver to react and hit the brakes impacts the overall stopping distance. The longer the reaction time, the greater the distance covered before hitting the brakes.
- Road Conditions: The condition of the road, whether it is dry or wet, affects the grip between the tires and the road surface, which in turn influences the stopping distance.
