Question

Among the four graphs, there is only one graph for which average velocity over the time interval $(0, T)$ can vanish for a suitably chosen $T$ . Which one is it ?

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

Answer 2

In the graph (b), for one value of displacement, there are two timings. As a result of it, for one time, the average velocity is positive and for other time is equal but negative. Due to it the average velocity for timings (equal to time period) can vanish.
