Answer 1

Answer:

Explanation:

Friction force;

In opposite direction

Answer 2

The contact force which is responsible in bringing the car to rest is called as Frictional force.

• The direction of the frictional force is always opposite to that of the motion of the object.
• In this case, the frictional force will act in the direction opposite to the motion of the car.
• That is why, when the brakes are applied, due to the frictional force the speed of the car is reduced and finally it comes to rest.
