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=(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.
