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