Yes, it is possible to have a situation where an object is accelerating and has a velocity of zero. This happens when the object is changing its direction of motion. For example, imagine a car moving with a velocity of 30 mph to the right. If the car suddenly applies the brakes, it will begin to decelerate, and its direction of motion will change. When the velocity of the car becomes equal to zero, it will continue to decelerate for a brief period before it comes to a complete stop with its velocity being zero, but still accelerating due to the force applied by brakes. Hence, in cases where an object changes its direction of motion, it is possible to have an object accelerating while its velocity is zero.
