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

Text Solution

Verified by Experts

No, it is not possible, in order to make velocity zero in an infinitesimally . Small internal of time, the car needs an infinite deceleration which in not possible .
