Answer: The correct option is (A) -8.3 m/s.
Step-by-step explanation: Given that an object moves along the -axis and the graph shows its position as a function of time.
We are to find the average velocity of the object from points B to C.
From the graph, we see that
the co-ordinates of the point B are (3, 25) and that of C are (6, 0).
That, is (x, t) = (3, 25) and (6, 0).
Therefore, the average velocity of the object from points B to C is given by
[tex]A_v=\dfrac{x(6)-x(3)}{6-3}=\dfrac{0-25}{3}=-\dfrac{25}{3}=-8.3[/tex]
Thus, the required average velocity of the object from points B to C is -8.3 m/s.
Option (A) is CORRECT.
