Question

Example 3.8 Reaction time : When a
situation demands our immediate
action. It takes some time before we
really respond. Reaction time is the
time a person takes to observe, think
and act. For example, if a person is
driving and suddenly a boy appears on
the road, then the time elapsed before
he slams the brakes of the car is the
reaction time. Reaction time depends
on complexity of the situation and on
an individual.
You can measure your reaction time
by a simple experiment. Take a ruler
and ask your friend to drop it vertically
through the gap between your thumb
and forefinger (Fig. 3.15). After you
catch it, find the distance d travelled
by the ruler. In a particular case, d was
found to be 21.0 cm. Estimate reaction
time.​
