Respuesta :

The acceleration will be zero when speed is plotted against time.

As the velocity slope is a straight line when distance time graph is considered. Straight slope indicates increasing velocity constantly with time.

Acceleration:

                    The rate of change of velocity with respect to time. it is a vector quantity (both magnitude and direction). SI unit of acceleration is given as meter/second square

        speed= Distance/Time

        Acceleration = velocity/ Time

acceleration is equal to differentiation of velocity with time.

  (differentiation of constant= zero)

differentiation of constant velocity gives zero acceleration.

Thus  the graph with constant velocity acceleration will be zero.
