A velocity-time graph is shown, displaying the behavior of a race cart along a linear track. During the time intervals between 40-50 min, it would travel in a negative direction, therefore the correct answer is option D.
What is Velocity?
The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
As you can observe from the graph the displacement of the race cart is negative during the time interval of 40-50 min
The area under the velocity time curve repr3sent the displacement of the object.
Thus, a velocity-time graph is displayed to show the movement of a race cart along a straight line. It would move in the negative direction between 40 and 50-minute intervals. therefore the correct answer is option D.
