Among the four-graph shown in the figure, there is only one graph for which average
velocity over the time interval 
can vanish for a suitably chosen 
. Which one is it?
Text Solution
Verified by ExpertsB
In graph for one value of displacement, there are two different points of time. Hence, for one time, the average velocity is positive and for other time is equivalent negative.
As there are opposite velocities in the interval 
to 
, hence average velocity can vanish in . This can be seen in the figure alongside.
Here, 
(same displacement) for two different points of time.
