The reaction time for an automobile driver is 0.7 sec. If the automobile can be decelerated at 5 m/s2, calculate the total distance travelled in coming to stop from an initial velocity of 8.33 m/s when a signal is observed.
Distance travelled before brakes are applied = 8.33 x 0.7 = S1
and stopping distance
total distance = S1 + S2 = 12.77 m.
