Question

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.

Easy
Solution

Distance travelled before brakes are applied = 8.33 x 0.7 = S1
and stopping distance =U22a=(8.33)22×5=S2
total distance = S1 + S2 = 12.77 m.
