Assume you are driving a car at a constant speed of 80.0 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.127 sec. The brakes provide an acceleration of -5.5 m/s2. Find the distance (in m) the car travels (at 80.0 km/h) during your reaction time.   Calculate the total distance (in m) traveled by the car before stopping.

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 –
