Is it possible that the brakes of a car are so parfect that car stops instantaneously . If not give reason.

Is it possible that the brakes of a car are so perfect that the car stops instantaneously ?

A car is moving on a straight horizontal road with a speed v. When brakes are applied to give a constant retardation a, the car is stopped in a shortest distance S. If the car was moving on the same road with a speed 3v and the same retardation a is applied, the shortest distance in which the car is stopped will be

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.

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

A driver of a car travelling at 52 km h^-1 applies the brakes and accelerates uniformly in the opposite direction. The car stops in 5 s. Another driver going at 3 km h^-1 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 travelle farther after the brakes were applied?

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 ?
