Answer :
Adults with good attention spans typically have reaction times of 0.75 seconds or less. 28 m/s is equal to 100 km/h in velocity.
What is meant by velocity?
The direction of moving mass or object depends on its velocity. Speed can be thought of as a real number in its simplest form. Velocity is essentially a vector quantity. It is the speed at which distance is changing. The problem is the displacement change rate.
Briefing:
The distance before the car comes to a complete stop increases during the reaction time since the vehicle is still moving at a constant speed.
Adults with good attention spans typically have reaction times of 0.75 seconds or less.
=100 km/1 h
=100000m/3600s
=28 m/s .
Consequently, the car moves 21 meters in 0.75 seconds.
