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.

A driver takes 0.20 second to apply the brakes (reaction time). If he is driving car at a speed of 54kmh^(-1) and the brakes cause a deceleration of 6.0ms^(-1) ? Find the distance travelled by car after he sees the need to put the brakes.

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.

A driver of car takes -20 s (which is the reaction time of dricer ) to apply the brkes after he sees an obstruction at a distance of 25 m from him . If he is driving car at a speed of 54 km h^(-1) and the brakes cause a deceleration of 6.0 km h^(-2), predict whether he will avert collistion or not.

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 applies the brakes on seeing traffic signal 400m ahead. At the time of applying of brakes vehicle was moving with speed 15 m//s . The brakes provide uniform deceleration of 0.3m//s^(2) . The displacement of the vehicle in 1min duration after the driver sees the signal is :

A car is travelling at a speed of 90 km/h. Brakes are applied so as to produce a uniform acceleration of – 0.5 m/s2. Find how far the car will go before it is brought to rest?

A driver applies the brakes on seeing traffic singal 400m ahead. At the time of applying of brakes vehicle was moving with speed 15 m//s . The brekes provide uniform deceleration of 0.3m//s^(2) . The displacement of the vehicle in 1 mmin duration after the driver sees the singal is :

A person driving a car with a speed 72 km/h suddenly sees a boy crossing the road. If the distance moved by car, before the person applies brakes is 5 m, the reaction time of the person is
