A driver is driving a car at a speed of 90km/h. he spots a child standing on his way and decided to apply the brakes but it took him 0.3s to actually apply the brakes. If the retardation produced by the brakes is 10m//s^(2) , calcualtion the total distance covered by car before coming to rest

The driver of a car travelling at speed v suddenly sees a wall at a distance r directly infront of him. To avoid collision, should he apply the brakes or turn the car sharply away from the wall ? Give reason.

    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 ?

    When brakes are applied on a moving car, the car dips to the front. Why ? [That is try to show that front wheels are more pressed as compared to rear ones when the brakes are applied]. Assume that centre of mass of the car is equidistant from the front and rear wheels.

    What will happen to the speed of a car when the driver applies brakes ?

    A car is moving with a constant speed. The wheels of the car make 120 rotations per minute. The brakes are applied and the car comes to rest in 8 second. How many rotations are completed by the wheels, before the car is brought to rest? (Assume that the brakes produce a constant retarding force)

    By applying the brakes without causing skid, the driver of a car is able to stop his car with in a distance of 5 m , if it is going at 36 kmph . If the car were going at 72 kmph . Using the same brakes, he can stop the car over a distance of
