What is the acceleration of a car that travels in a straight line at a constant speed?

That's exactly the definition of zero acceleration ... no change in speed or direction.

If the object travels in straight lines and has constant speed then there is no acceleration. That means zero acceleration.

The acceleration of a car traveling in a straight line at a constant speed is zero, as there is no change in speed or direction. Since acceleration is defined as a change in velocity, and in this case there is none, the car maintains a constant velocity. Thus, the acceleration can be mathematically expressed as 0 m/s².
