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 . 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. From the graph determine which of the two cars travelled further after brakes were applied and by how much distance it travelled?

A car of 1000kg moves with a velocity 20m//s . On applying brakes it comes to rest in 5s. What is the final momentum?

A car of 1000kg moves with a velocity 20m//s . On applying brakes it comes to rest in 5s. What is the initial momentum?

A car of 1000kg moves with a velocity of 10 m/s. On applying brakes it comes to rest in 5s. Then what are its initial momentum and final momentum?

A car and motorcycle moving in the same direction with velocities 15 m//s and 20m/s respectively. The motorcycle overtakes the car at certain instant. At what time there after will they be at 250 m apart ?

A car moving with a speed of 108km/h comes to rest after 4s on applying brake. If the mass of the car including the passengers is 1000kg, what will be the force apllied when brake is applied ?

A car travelling at a speed of 54 km/hr is brought to rest in 90 s. Find the distance travelled by the car before coming to rest.
