Question

The driver of a car sees an obstacle in the road and stops the car
as quickly as possible The Car stops without hitting the obstacle
State three factors that could affect the stopping distance of the
car

Pranay Kumar · Accepted Answer

Solution :-
There are following three factors that could affect the stopping
distance
1 Reaction Time : it is time taken by driver to apply the brake
when the drive sees an obstacles During this time
car moved towards the obstacles without retardation and stopping
distance get reduced

2 Frictional Force : It is the force of friction offered by road on
the tyre of car and frictional force depends on tyre
material ,tyre tread depth , roughness of road and weight of the
car
3 Stopping Distance : the distance between car and obstacles
