A driver travelling at 90 kph applied the brakes for 5 s. If the braking acceleration was `2 m//s^(2)`, what was her final speed ?

A person travelling at 43.2 km/h applies the brake giving a deceleration of 6.0 m/ss^2 to his scooter. How far will it travel before stopping?

A train is travelling at a speed of 90 km//h . Brakes are applied so as to produce a uniform acceleration of - 0.5 m//s^(2) . Find how far the train will go before it is brought to rest.

a driver of a car travelling at 52 km//h applies the brakes and acceleration uniformly in the opposite direction. The car stops in 5 s . Another driver going at 34 km//h in another car applies his brakes slowly and stops in 10 s . On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied ?

A car is moving with constant speed 15 m//s . Suddenly the driver sees an obstruction on the road and takes 0.40 s to apply the brake, the brake causes a deceleration of 5 m//s^(2) . Find the distance traveled by the car before it stops.

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 ?

The brakes of a train which is travelling at 30 m//s are applied as the train passes point A. The brakes produce a constant retardation of magnitude 3lambda m//s^(2) until the speed of the train is reduced to 10 m//s . The train travels at this speed for a distance and is then uniformly accelerated at lambda m//s^(2) until it again reaches a speed of 30 m//s as it passes point B. the time taken by the train in travelling from A to B, a distance of 4 km, is 4 min. Sketch the speed time graph for this motion and calculate:- (i) The value of lambda (ii) Distance travelled at 10 m//s .

A driver travelling at 30 kph sees the light turn red at the intersection. If his reaction time is 0.6s , and the car can decelerate at 4.5 m//s^(2) , find the stopping distance ofthecar. What would the stopping distance be ifthe car were moving at 90 kph.

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 :

On seeing red light ahead, a driver takes 0.3 s to apply the brakes. This is called the reaction time of the driver. If he was initially driving at a speed of 36km/hr and application of the brakes causes a deceleration of 4.0m//s^(2) . Calculate the distance travelled by the car after he sees the red light.
