When a car driver travelling at a speed of 10 m/s applies brakes and brings the car to rest in 20 s, then retardation will be :

A car travelling at a speed of 20 ms^-1 applies brackes and stops within 10s. What is the acceleration of car?

A car travelling at a speed of 10m/s stops in 4s after the application of brakes. If we assume the retardation to be constant. Find the retardation.

A car travelling at a speed of 10m/s stops in 4s after the application of brakes. If we assume the retardation to be constant. Find the distance travelled during this time.

A car is travelling on road at 50kmh^-1 . The driver applies brakes and brings the car to rest. Which frictional force does more work: (a) the force between the wheels and the brakes or (b) the force between the wheels and the road?

A driver of a car A travelling at 54 km//h applies the brakes and stops the car in 4 seconds. Another driver of car B travelling at 36 km//h applies the brakes and stops the car in 6 seconds. Plot speed versus time graphs for the two car. which of the cars travelled farther before stopping ?
