Question

Four similar cars having exactly the same mass are running at the same speed on the same road when brakes are applied at the same time. The cars come to a stop after covering distances of 6 m, 5.5 m, 4.2 m and 3.4 m respectively. The friction between the brake pads and discs will be the maximum in the car which travels the distance of:
6 m
5.5 m
3.4 m
4.2 m​

Answer 1

Answer:

3.4 m

Step-by-step explanation:

Cars would stop depending on friction between their brake pads and discs.

The larger the friction the sooner the car will come to stop.

As we can see that car which travelled 3.4m stops sooner than all the other cars so we can say that frictional force was maximum in it.
