Stoke's law states that retarding force is proportional to velocity. An example is falling rain drop in air.

My book states that " if a rain drop falls, it accelerates initially due to gravity. As the velocity increases, the retarding force force also increases. Finally, when viscous force plus buoyant force becomes equal to force due to gravity,the net force becomes zero and so does the acceleration.

The rain drop then descends with a constant velocity

My question is, if acceleration is zero, how the rain drop would move with constant velocity?
