A drunk man was driving his car at a speed of 25.0 m/s (or 90 kph) when he saw a cow in the middle of the road, 50.0 m away from him. It took him 0.400 s to react at which the car was moving at constant speed. After that, he stepped on the brakes to stop at a rate of 6.00 m/? . Is this acceleration enough to save him and the cow from an accident?

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
