Question

An object moves along the -axis. The graph shows its position as a function of time . Find the average velocity of the object from points B to C

Answer 1

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

$A_v=\dfrac{x(6)-x(3)}{6-3}=\dfrac{0-25}{3}=-\dfrac{25}{3}=-8.3$

Thus, the required average velocity of the object from points B to C is -8.3 m/s.

Option (A) is CORRECT.

Answer 2

Average velocity = distance / time

=(0-25) / (6-3)

= -8.3 answer
