Is the acceleration zero for this entire velocity graph?

Homework Equations

v = delta x/ delta t
a= delta v/ delta t

The Attempt at a Solution

If i were to convert this velocity graph to an acceleration graph, i think it would be a straight line on the t-axis.

yes, the velocity is constant all the time, it just changes instantaneously at t=3 and at t=6. If there were non-zero acceleration the velocity would change over time and you would see a slope (upwards or downwards) in a velocity versus time graph.

thank you very much for the reply,

but just to make sure: so the acceleration graph of this velocity graph would be just a straight line on the t-axis ( 0 acceleration) ?

yes that's correct
