Question

The graph of the x-coordinate of a particle going along the x-axis as a function of time is shown in figure. The average velocity during 0 to 25 s is

Answer 1

The average velocity during 0 to 25 s is zero

Explanation:

The graph is attached

We know that

$\text{Average Velocity}=\frac{\text{Total Displacement}}{\text{Total Time}}$

From the graph it is clear that the particle starts from rest and in 25 seconds it  comes again in rest

Therefore, the total displacement of the particle in 25 seconds is zero

Thus, the average velocity of the particle is zero.

Hope this answer is helpful.

Answer 2

Explanation:

The question statement is incomplete as there is no graph mentioned in the question.

In general the formula of velocity is;

Velocity = Displacement / time

Now when we take the average velocity, we will simply consider the total displacement and also the overall time under consideration. And from the difference in velocity, the concept of acceleration comes which can be zero, positive or even negative.
