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.

A driver travelling at speed 36 kmh^(-1) sees the light trun red at the intersection. If his reaction time is 0.6s, and then the car can deaccelerate at 4 ms^(-2) . Find the stopping distance of the car.

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 ?

the reaction time for an automobile drive os 0.6s if the automobile can be decelerated at 5 ms^(-2) , calculate the total distance travelled in coming to stop fro, an intial velocity of 30kmh ^(-1) after a singnal is observed.

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.

Two cars are travelling towards each other on a straight road at velocities 15 m//s and m//s respectively. When they are 150 m apart both the drivers apply the brakes and the car decelerate at 3 m//s^(2) and 4 m//s^(2) until they stop separation between the cars when they come to rest is

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 car is moving with speed 20 m//s . Suddenly the driver sees the sign of danger at a distance of 50 m , after a certain reaction time t_(0) , he applies breaks to cause deceleration 5 m//s^(2) . What is the maximum allowable reaction time t_(0) to avoid accident and distance traveled by the car during reaction time?

A particle starts from rest accelerates at 2 m//s^2 for 10 s and then goes for constant speed for 30 s and then decelerates at 4 m//s^2 till it stops. What is the distance travelled by it.
