If the driver of a car A which is running at a speed of 54 km/h applies brakes, the car stops in 5 sec.

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 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 ?

A driver takes 0.20 s to apply the brakes after he sees a need for it. This is called the reaction time of the driver. If he ils driving a car at a speed of 54 km/h and the brakes cause a deceleration of 6.0 m/s^2 , find the distance travelled by the car after he sees the need to put the brakes on.

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.

The driver of a car moving with a speed of 10 ms^(-1) sees a red light ahead, applies brakes and stops after covering 10 m distance. If the same car were moving with a speed of 20 ms^(-1) the same driver would have stopped the car after covering 30 m distance. Within what distance the car can be stopped if traveling with a velocity of 15 ms^(-1) Assume the same reaction time and the same deceleration in each case

When the driver of a fast moving car suddenly applies brakes, the passengers in the car

A driver having a definite reaction time is capable of stopping his car over a distance of 30 m on seeing a red traffic signal, when the speed of the car is 72 km/hr andover a distance of 10 m when the speed is 36 km/hr. Find the distance over which he can stop the car if it were running at a speed of 54 km/hr. Assume that his reaction time and the deceleration of the car remains same in all the three cases.

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 ?
