If two automobiles have the same acceleration, do they have the same
velocity? Why or why not?

No

Explanation:

Acceleration = Velocity/Time

An example of where the velocity would be different is:

Acceleration = (automobile 1)

Acceleration = (automobile 2)

As you can see, the velocity for the first automobile is 10 m/s while the second one has a velocity of 25 m/s (with a greater time travelled) and both resulted in the same acceleration of 5 m/s².
