Two cars A and B travelling with speed 20m/s and 10m/s respectively applied brakes, so that A comes to rest in 15 second and B in 7.5s . Draw the velocity time graph of A and B in the same graph.

Two cars A and B travelling with speed 20m/s and 10m/s respectively applied brakes, so that A comes to rest in 15 second and B in 7.5s . In the above process, the wear and tear of which the cars get affected more?

Two cars A and B travelling with speed 20m/s and 10m/s respectively applied brakes, so that A comes to rest in 15 second and B in 7.5s. From the graph determine which of the two cars travelled further after brakes were applied and by how much distance it travelled?
