A) The particle has never turned around.
B) The particle has zero displacement.
C) The average speed in the interval 0 s to 10 s is the same as the average speed in the interval 10 s to 20 s.
D) Both (A) and (B)
Correct Answer: C
Solution :
The distance is the total area under the v - t graph. Since the area of speed time graph for time interval of 0 to 10 s is the same as area of speed time graph for 10 s to 20 s. Hence average speed is same in these intervals.
