Question

At which section does the object move with a positive velocity

Answer 1

The velocity of any objetc is defined in terms of initial and final position of the object is,

$v=\frac{d_f-d_i}{t}$

As in the graph during the motion of object, the final position of the object is decreasing with time. Thus, the final position is always less than the initial position.

$d_f-d_i<0$

Thus, the value of velocity at every point is,

$v<0$

Hence, first option (This object never has a positive velocity) is the correct answer.
